(Acetonitrile-1κN)[μ-1H-benzimidazole-2(3H)-thione-1:2κ2S:S][1H-benzimidazole-2(3H)-thione-2κS]bis(μ-1,1-dioxo-1λ6,2-benzothiazole-3-thiolato)-1:2κ2S3:N;1:2κ2S3:S3-dicopper(I)(Cu—Cu), [Cu2(C7H4NO2S2)2(C7H6N2S)2(CH3CN)] or [Cu2(tsac)2(Sbim)2(CH3CN)] [tsac is thiosaccharinate and Sbim is 1H-benzimidazole-2(3H)-thione], (I), is a new copper(I) compound that consists of a triply bridged dinuclear Cu—Cu unit. In the complex molecule, two tsac anions and one neutral Sbim ligand bind the metals. One anion bridges via the endocyclic N and exocyclic S atoms (μ-S:N). The other anion and one of the mercaptobenzimidazole molecules bridge the metals through their exocyclic S atoms (μ-S:S). The second Sbim ligand coordinates in a monodentate fashion (κS) to one Cu atom, while an acetonitrile molecule coordinates to the other Cu atom. The CuI—CuI distance [2.6286 (6) Å] can be considered a strong `cuprophilic' interaction. In the case of [μ-1H-benzimidazole-2(3H)-thione-1:2κ2S:S]bis[1H-benzimidazole-2(3H)-thione]-1κS;2κS-bis(μ-1,1-dioxo-1λ6,2-benzothiazole-3-thiolato)-1:2κ2S3:N;1:2κ2S3:S3-dicopper(I)(Cu—Cu), [Cu2(C7H4NO2S2)2(C7H6N2S)3] or [Cu2(tsac)2(Sbim)3], (II), the acetonitrile molecule is substituted by an additional Sbim ligand, which binds one Cu atom via the exocylic S atom. In this case, the CuI—CuI distance is 2.6068 (11) Å.

[Cu4(tsac)4(CH3CN)2].2CH3CN, (I), was synthesized as reported
previously (Dennehy et al., 2007). [Cu2(tsac)2(Sbim)2(CH3CN)],
(II), was synthesized by dropwise addition of a red solution of
[Cu4(tsac)4(CH3CN)2].2CH3CN (10 mg, 0.04 mmol of Cu+) in CH3CN
(5 ml) to another solution of 2-mercaptobenzimidazole (6 mg, 0.04 mmol) in
CH3CN (4 ml) with mechanical stirring. The solution turned orange. After a
day of slow evaporation of the solvent, red crystals of (II) suitable for
X-ray diffraction studies were obtained. The crystals were washed with diethyl
ether and were air stable. Compound (II) was synthesized employing different
molar ratios of (I) and Sbim (Cu:Sbim = 1:1, 1:4, 1:10) in CH3CN solutions.
When the molar ratio was 1:1 to 1:4, crystals of the title compounds were
obtained as unique products. When the Cu:Sbim ratio was 1:10, a very few thin
orange needles of (II) were obtained. Analysis, calculated for
C30H23Cu2N7O4S6: C 41.6, H 2.6, N 11.3%; found: C 41.6, H 2.3, N
11.3%. IR spectra were obtained in KBr dispersion and in Nujol mulls, and
showed no differences in the vibrational bands. The IR spectra of this complex
confirm the presence of two different thiosaccharinate anions. Selected anion
bands, KBr (cm-1): 1394 (w)/1355 (s), 1258 (s),
1234/1222 (w), 1149 (vs), 1118 (m), 1022 (vw)/1008
(m), 837 (m)/822 (m), 622 (w). The UV–Vis spectra
of the solid complex presents broad bands (200/214/245 and 298/310 nm) that
are assigned to transitions in the phenyl groups and in the thiocarbonilic
bonds within the ligands.
For (I), the H atoms were positioned geometrically and treated as riding, with
C—H = 0.93–0.96 Å and N—H = 0.86 Å. H atoms bonded to tertiary C
atoms were refined with Uiso(H) = 1.2Ueq(C), while for the
methyl groups Uiso(H) = 1.5Ueq(C). The anisotropic
displacement ellipsoid of atom S1D displays a marked elongation in the
normal direction to both the S—C and S—Cu bonds. This can be related to
the motion of the corresponding Sbim molecule, which coordinates to Cu
via only one bond through atom S1D. The highest residual
electron-density peak is located 0.79 Å from atom S1D.
In the case of (II), refinement proceeded in a similar manner. The main
difference arises in the treatment of the disordered Sbim(D) molecule,
which was refined in two orientations. The atomic displacements for
Sbim(D) were refined isotropically because of the proximity between
atoms belonging to the two disordered positions. Anisotropic treatment of the
atomic displacement did not provide better statistics considering the increase
of variables in the refinement. Finally, the distance between the closest
atoms in the Sbim(D) molecule were restrained to the average distance
of the rest of the Sbim molecules in the complex. The C7—N1 and C7—N2
distances were restrained to 1.33 Å and the N1—N2 distance was restrained
to 2.145 Å. The position of the highest residual electron-density peak is
located 2.44 Å from atom H4DA.

Empirical absorption correction using spherical harmonics,
implemented in SCALE3 ABSPACK scaling algorithm. |
Geometry. All s.u.'s (except the s.u. in the dihedral angle between two l.s. planes) are
estimated using the full covariance matrix. The cell s.u.'s are taken into
account individually in the estimation of s.u.'s in distances, angles and
torsion angles; correlations between s.u.'s in cell parameters are only used
when they are defined by crystal symmetry. An approximate (isotropic)
treatment of cell s.u.'s is used for estimating s.u.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor
wR and goodness of fit S are based on F2, conventional
R-factors R are based on F, with F set to zero for
negative F2. The threshold expression of F2 >
2σ(F2) is used only for calculating R-factors(gt) etc.
and is not relevant to the choice of reflections for refinement.
R-factors based on F2 are statistically about twice as large
as those based on F, and R-factors based on ALL data will be
even larger. |

Empirical absorption correction using spherical harmonics,
implemented in SCALE3 ABSPACK scaling algorithm. |
Geometry. All s.u.'s (except the s.u. in the dihedral angle between two l.s. planes)
are estimated using the full covariance matrix. The cell s.u.'s are taken
into account individually in the estimation of s.u.'s in distances, angles
and torsion angles; correlations between s.u.'s in cell parameters are only
used when they are defined by crystal symmetry. An approximate (isotropic)
treatment of cell s.u.'s is used for estimating s.u.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and
goodness of fit S are based on F2, conventional R-factors R are based
on F, with F set to zero for negative F2. The threshold expression of
F2 > 2σ(F2) is used only for calculating R-factors(gt) etc. and is
not relevant to the choice of reflections for refinement. R-factors based
on F2 are statistically about twice as large as those based on F, and R-
factors based on ALL data will be even larger. |

Thionates, anions produced by the deprotonation of heterocyclic thioamides, can coordinate to metals, producing mononuclear or complex polynuclear species. Like other thioamides, thiosaccharin [or 1,1-dioxo-1λ6,2-benzothiazole-3(2H)-thione] is a versatile ligand, with the ability to coordinate metal centres in many ways (Dennehy et al., 2009). Particular attention has been devoted in recent decades to the synthesis of copper complexes, in both the mono- and divalent oxidation states, due to the great variety and flexibility of their coordination environments (Rapper, 1994). Most of the chemistry of CuI with thionates has been focused on the tetra- or hexanuclear binary complexes (García-Vázquez et al., 2005; Ruan & Shi, 2007; López-Torres et al., 2006). We have been working with binary and ternary copper thiosaccharinates, firstly synthesizing the Cu(tsac) complex (where tsac is the thiosaccharinate anion), which crystallized as the tetranuclear cluster [Cu4(tsac)4(CH3CN)2].2CH3CN from acetonitrile solutions (Dennehy et al., 2007), and then ternary phosphane complexes (Dennehy et al., 2009). To study the competition between two different thiones bound to copper, we have synthesized a ternary thiosaccharinate with thiosaccharin and 1H-benzimidazole-2(3H)-thione (Sbim), viz. [Cu2(tsac)2(Sbim)2(CH3CN)], (I), and [Cu2(tsac)2(Sbim)3], (II).
Compound (I) is a copper(I) thiosaccharinate and crystallizes in the space group P1. It is built of triply bridged dinuclear units. Two tsac anions and one Sbim molecule bind the metals. One anion bridges via the endocyclic N and exocyclic S atoms (µ-S:N), with Cu—N and Cu—S distances of 2.000 (2) and 2.2799 (9) Å, respectively. The other anion and one of the Sbim molecules bridge the metal centres through their exocyclic S atoms, with Cu—S distances of 2.3743 (9) and 2.6711 (10) Å for tsac, and 2.3785 (10) and 2.3901 (10) Å for Sbim. The second Sbim molecule coordinates in a monodentate fashion (κS), with a Cu—S distance of 2.2091 (10) Å, and the coordination of Cu2 is completed by an acetonitrile molecule, with a Cu—N distance of 1.964 (3) Å. Each CuI atom has a nearly distorted tetrahedral coordination environment. Given the proximity of the two CuI atoms, with a CuI—CuI distance of 2.6285 (6) Å, the two subunits form tetrahedra linked by edge-sharing. This short CuI—CuI distance indicates a strong cuprophilic interaction.
Each [Cu2(tsac)2(Sbim)2(CH3CN)] structural unit of (I) is stabilized by two intramolecular hydrogen bonds (N1D—H2DA···O1B and N1C—H1C···N1A) and one intermolecular hydrogen bond [N1D—H1DA···O1Ai; symmetry code: x, -y + 1, -z + 1], establishing an interaction with another inversion-symmetry related [Cu2(tsac)2(Sbim)2(CH3CN)] unit. The N2C—H2CA bond points towards a neighbouring Cu—Cu centre and away from acceptors. Therefore, it is blocked and unable to participate in any hydrogen bonds. Additionally, two Sbim and two tsac planar residues stack together through their six-membered planar rings in a four-layer group, with the negative tsac residues separated by the neutral Sbim molecules. There are also π–π interactions, with the rings arranged in the order tsaciii/Sbim/Sbimiv/tsacv [symmetry codes: (iii) x+1, y, z; (iv) -x+2, -y+1, -z; (v) -x+1, -y+1, -z]. Centroid–centroid distances are 3.588 (2) Å for tsaciii–Sbim (rings C1A–C6A and C1C–C6C, respectively) and equivalent Sbimiv–tsacv interactions; and 3.616 (2) Å between parallel Sbim–Sbimiv. The dihedral angle between tsac anions and nearby Sbim molecules is 12.53 (16)°.
Compound (II) crystallizes in the monoclinic space group P21/c. As mentioned before, this structure presents important similarities with the structure of (I). In the case of (II), the acetonitrile molecule is substituted by an additional disordered Sbim molecule, which binds to Cu from the exocyclic S atom (κS). In this case, the tsac anion bridges via the endocyclic N and exocyclic S atoms (µ-S:N), with Cu—N and Cu—S distances of 2.047 (4) and 2.3057 (17) Å, respectively. Each CuI atom presents a distorted tetrahedral coordination environment and both tetrahedra are linked by edge-sharing. The other anion and one of the Sbim molecules bridge the metal centres through their exocyclic S atoms, with Cu—S distances of 2.5470 (16) and 2.3261 (15) Å for tsac, and 2.4795 (15) and 2.3264 (15) Å for Sbim. The second Sbim molecule coordinates in a monodentate fashion (κS), with a Cu—S distance of 2.2748 (16) Å. An important difference between these two structures is the CuI—CuI distance; in the case of (II), the distance is 2.6068 (11) Å, which is slightly shorter than that in (I). Comparing the Cu—N distances, that in (I) is considerably shorter than that in (II), which leads to a weaker CuI—CuI interaction in (I). [Please check rephrasing - original text was not clear.]
The three-dimensional crystal structure of (II) is sustained by two intramolecular hydrogen bonds (N1C—H1C···N1A and N2DA—H2DA···O2B) and one intermolecular hydrogen bond (N1DA—H1DA···O1Av [symmetry code: (v) -x, -y + 1, -z] which correspond to a molecule related by inversion symmetry. The last two bonds involve the interaction between the disordered Sbim(D) molecule and two tsac molecules from two symmetry-related [Cu2(tsac)2(Sbim)3] units, as shown in Fig. 4. Finally, a possible intermolecular C—H···π interaction was identified as being responsible for the orientation of the Sbim(B) molecule, and responsible for the infinite packing along the plane defined by the [100] and [010] basis vectors. The C2E—H2E···Cg (Cg is the centroid of the S2B/N1B/C7B/C6B/C1B ring) angle is 162° and the H2E···Cg distance is 2.77 Å.
In order to compare the conformational geometries of (I) and (II), we performed a least-squares plane fitting of all the Sbim and tsac molecules in the two compounds, and the results are presented in Tables 1 and 2. The planes are constituted by atoms S1/S2/N1/C1/C2/C3/C4/C5 for Sbim and S1/N1/N2/C1/C2/C3/C4/C5/C6/C7 for tsac molecules. According to the calculations, the r.m.s. deviations of the fitted atoms are all below the limit of 0.0450 Å. A further comparison, assuming a common Cu1—Cu2 core, allows us to estimate the angles between the same kind of molecules in both conformations as 17.7, 14.2, 15.1 and 83.7° for tsac(A), tsac(B), Sbim(C) and Sbim(D), respectively (see Fig. 5). In the case of Sbim(D), we included the conformation with the higher site-occupation number, corresponding to Sbim(DA).
