Two W/Cu/S clusters: tetra­ethyl­ammonium bromidodi-μ2-sulfido-sulfido­[tris­(3,5-dimethyl­pyrazol-1-yl)­borato]copper(I)tungsten(VI) and tetra­ethyl­ammonium dibromido-μ3-sulfido-di-μ2-sulfido-[tris­(3,5-di­methyl­pyrazol-1-yl)borato]dicopper(I)­tungsten(VI)

Z. Wei and X. You
The reaction of (Et4N)[Tp*WS3] [Tp* = hydrogen tris­(3,5-dimethyl­pyrazol-1-­yl)borate] with one or two equivalents of CuBr afforded the [1 + 1] and [1 + 2] addition products (Et4N)[Tp*WS(μ-S)2(CuBr)] {or (C8H20N)[CuWBr(C15H22BN6)S3], (I)} and (Et4N)[Tp*W(μ3-S)(μ-S)2(CuBr)2] {or (C8H20N)[Cu2WBr2(C15H22BN6)S3], (II)}. The anion of (I) contains a [W(μ-S)2Cu] core formed by the addition of one CuBr unit to the [Tp*WS3] species. The anion of (II) has a butterfly-shaped [W(μ3-S)(μ-S)2Cu2] core formed by the addition of two CuBr units to the [Tp*WS3] species. The [Tp*WS3] sections of each complex exhibit approximate C3v point symmetry and have closely comparable geometry. In (II), both the anion and cation lie on a crystallographic mirror plane. The structure of (I) is noncentrosymmetric and polar.

Comment top

In the past decades, the chemistry of Mo(W)/Cu/S clusters derived from reactions of metal sulfide synthons such as [MOxS4-x]2- or [Cp*MS3]- (M = Mo or W, x = 0–3, Cp* = pentamethylcyclopentadienyl) with CuX (X = Cl, Br, I, NCS, CN) has been investigated extensively because of their novel structures (Chisholm et al., 2002; Parkin, 2004; Zulys et al., 2005) and their potential applications in biological systems (Lewinski et al., 2006) and opto-electronic materials (Vahrenkamp, 1999). Among these Mo(W)/Cu/S clusters, a complete series of products obtained by the stepwise addition of CuX has not previously been realized in a system involving the same components CuX and [MS4]2- or [EMS3]n- (E = O, n = 2 or E = Cp*, n = 1) in different molar ratios (Bunge et al., 2007; Boomishankar et al., 2006; Malik et al., 1997; Kaupp et al., 1991). Recently, we have investigated the preparation of Mo(W)/Cu/S clusters from the precursor (Et4N)[Tp*WS3], where Tp* = hydrogen tris(3,5-dimethylpyrazolyl)borate (Seino et al., 2001), and this compound has been found to undergo stepwise addition reactions with one to four equivalents of CuNCS to yield the products [Tp*WS3(CuNCS)n]- (n = 1 or 2), [Tp*WS3(CuNCS)3Br]2- and the polymeric {Tp*WS3(CuNCS)4}- (Wei, Li, Ren et al., 2009). In continuation of our work in this area, we treated the precursor (Et4N)[Tp*WS3] with one to three equivalents of CuBr in a stepwise manner (Fig. 1), and obtained the [1+1], [1+2] and [1+3] products, (Et4N)[Tp*WS(µ-S)2(CuBr)], (Et4N)[Tp*W(µ3-S)(µ-S)2(CuBr)2] and (Et4N)[Tp*W(µ3-S)3(CuBr)3]. We have reported the crystal structure of the [1+3] product previously (Wei, Li, Cheng et al., 2009). Herein, we report the crystal structures of the [1+1] and [1+2] complexes, (I) and (II).

The anion of complex (I) comprises a [Tp*WS3]- unit and one CuBr group, with a pair of µ-S atoms forming a WS2Cu ring (Fig. 2). One terminal S atom is retained. The structure closely resembles that of the anion in the related compound (Et4N)[Tp*WS(µ-S)2(CuNCS)] (Wei, Li, Ren et al., 2009). It is noteworthy that the comparable [1+1] addition complex is not known among the M/Cu/S clusters based on the related precursor [PPh3][Cp*MS3], while for the (Et4N)[OMS3] precursor, reactions with one equivalent of CuCl and CuCN have been reported to yield the products [Me4N][WOS(µ-S)2(CuCl)] (Shamsur Rahman et al., 2000) and (Et4N)[MoOS(µ-S)2(CuCN)] (Zhang et al., 2008), respectively. In (I), atom Cu1 adopts a trigonal planar geometry, coordinated by one terminal Br atom and two µ-S atoms. The W1···Cu1 distance of 2.5893 (11) Å is slightly shorter than those in other butterfly-shaped or incomplete cubane core clusters. The terminal W1—S3 bond length of 2.141 (3) Å is similar to that in [WS4Cu2(dppm)3] [2.146 (4) Å] [dppm = bis(diphenylphosphino)methane] (Lang & Tatsumi, 1998), but slightly shorter than those in the corresponding precursor (Et4N)[Tp*WS3] (mean 2.193 Å) (Seino et al., 2001) and in the cluster (Et4N)[Tp*WS(µ-S)2(CuNCS)] [2.154 (3) Å] (Wei, Li, Ren et al., 2009). The mean W—µ-S (2.268 Å), Cu—µ-S (2.193 Å) and Cu—Br [2.2831 (14) Å] bond lengths are slightly longer than the corresponding values in the complex (Et4N)[Tp*WS(µ3-S)3(CuBr)3] (Wei, Li, Cheng et al., 2009).

The anion of complex (II) has a butterfly-shaped [WS3Cu2] structure in which one [Tp*WS3] unit and two CuBr groups are linked via one µ3-S and two µ-S atoms (Fig. 3). Atoms W1, S1, B1, N3, N4 and C6–C10 lie on a crystallographic mirror plane. Similar butterfly-shaped [WS3Cu2] cores have been observed in (Et4N)[Tp*WS3(CuNCS)2] (Wei, Li, Ren, et al., 2009), [PPh4][(Cp*WS3(CuCN)2] (Lang et al., 2004) and [MOS3M'2(PPh3)3] (M = W, Mo; M' = Cu, Ag) (Müller et al., 1983). Each Cu atom in (II) adopts a trigonal planar geometry, coordinated by one µ-S atom, one µ3-S atom and one terminal Br atom. The W···Cu distance of 2.6239 (10) Å is longer than that in complex (I), but similar to those found in other complexes containing three-coordinated Cu, such as (Et4N)[Tp*WS(µ3-S)3(CuBr)3] [2.6404 (2) Å] (Wei, Li, Cheng et al., 2009) and [PPh4][Cp*WS3(CuCN)2] [2.666 (3) Å] (Lang et al., 2004). Because of the coordination of the S atoms to the Cu atoms, the W1—S1 bond length of 2.331 (2) Å is longer than the W1—S2 bond length of 2.2293 (18) Å, and both bonds are elongated relative to the mean W—S bond length (2.193 Å) in the precursor (Et4N)[Tp*WS3] (Seino et al., 2001).

Fig. 4 illustrates how the S and Cu atoms of (I) and (II) build up sequentially towards the corners of a cubane-like unit. Firstly, one Cu atom is added to the Tp*WS3 unit to construct the [Tp*WS(µ-S)2Cu] core with one terminal S atom remaining. Secondly, the two Cu atoms in (II) form the butterfly core [Tp*W(µ-S)2(µ3-S)Cu2]. A third Cu atom can then be added to the butterfly core of (II) to produce an incomplete cubane-like unit, [Tp*W(µ3-S)3Cu3], as in the previously published structure (Et4N)[Tp*W(µ3-S)3(CuBr)3] (Wei, Li, Cheng et al., 2009). Throughout this sequence, the geometry of the [Tp*WS3] unit remains essentially unchanged: the r.m.s. deviations for overlay of the 26 non-H atoms in the core onto the precursor [Tp*WS3] are 0.14, 0.10 and 0.30 Å for (I), (II) and (Et4N)[Tp*W(µ3-S)3(CuBr)3], respectively. The [Tp*WS3] unit exhibits approximate C3v point symmetry and one of the mirror planes is retained as a crystallographic symmetry element in (II).

Packing diagrams are shown for (I) and (II) in Figs. 5 and 6, respectively. The structures contain comparable stacks of alternating complexes and Et4N+ cations running along the b axes. In (I), these stacks are arranged so that the Cu—Br bonds point towards the same direction along the c axis, forming a non-centrosymmetric and polar structure. In (II), the stacks are arranged in a centrosymmetric manner.

Experimental top

All manipulations were performed under an Ar atmosphere using standard Schlenk-line techniques. The precursor (Et4N)[Tp*WS3] was prepared as reported previously (Seino et al., 2001). For these reactions, CHCl3 is a better solvent than MeCN because CuBr is poorly soluble in CHCl3 and it can facilitate the stepwise introduction of CuBr into [Tp*WS3]-. Compound (I) is air sensitive and easily oxidized in solution to form (Et4N)[Tp*WO(µ-S)2(CuBr)]. Complex (II) is relatively air and moisture stable in the solid state.

For the synthesis of (I), to a solution of (Et4N)[Tp*WS3] (75 mg, 0.1 mmol) in 15 ml of CHCl3, CuBr (14.4 mg, 0.1 mmol) was added. After being stirred for half an hour, the resulting red solution was filtered and Et2O (30 ml) was carefully layered onto the surface of the filtrate. After 4 d, red prisms of (I) were collected by filtration, washed with Et2O and dried in vacuo. Yield: 72.3 mg {80% based on (Et4N)[Tp*WS3]}. Analysis: calculated C 32.46, H 4.98, N 11.52%; found C 32.32, H 4.55, N 11.95%.

UV–visible {MeCN, λmax [nm (ε M-1 cm-1)]}: 333 (14300), 445 (6400), 524 (3000). 1H NMR (400 MHz, CDCl3): δ 1.36–1.40 (t, 12H, CH2CH3), 2.37 (s, 9H, CH3 in Tp*), 2.95 (s, 9H, CH3 in Tp*), 3.33–3.39 (q, 8H, CH2CH3), 5.94 (s, 3H, CH in Tp*), the B—H proton was not identified.

For the synthesis of (II), to a solution of (Et4N)[Tp*WS3] (75 mg, 0.1 mmol) in 15 ml of CHCl3, CuBr (28.8 mg, 0.2 mmol) was added. A procedure identical to that used for (I) afforded dark red blocks of (II). Yield: 93 mg {85% based on (Et4N)[Tp*WS3]}. Analysis: calculated C 27.78, H 4.26, N 9.86%; found: C 27.32; H 4.55; N 9.95%.

UV–visible {MeCN, λmax [nm (ε M-1 cm-1)]}: 323 (16300), 420 (8890), 544 (5800). 1H NMR (400 MHz, DMSO-d6): δ 1.36–1.40 (t, 12H, CH2CH3), 2.37 (s, 9H, CH3 in Tp*), 2.96 (s, 9H, CH3 in Tp*), 3.31–3.38 (q, 8H, CH2CH3), 5.92 (s, 3H, CH in Tp*), the B—H proton was not identified.

Refinement top

H atoms were placed geometrically and constrained to ride on their parent atoms, with B—H = 0.98, C—H = 0.96 (methyl), 0.97 (methylene) or 0.93 Å (aromatic), and with Uiso(H) = 1.5Ueq(C) for methyl H atoms, or 1.2Ueq(C) otherwise. In compound (II), the methyl H atoms on C6 and C10 (in the pyrazole ring) and on C13 and C15 (in the Et4N+ cation) are disordered over the mirror plane.

Special details top

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds 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 > 2sigma(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.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'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 > σ(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.
