Treatment of ΛL-[Co(L-Hcys-N,S)(en)2](ClO4)2 with a mixture of 0.5 molar equiv. of AgClO4 and 0.5 equiv. of NaOH in water at room temperature gave a red solution, from which red crystals (I) were isolated by adding an aqueous solution of NaClO4.
H atoms bonded to C and N atoms were placed at calculated positions [C—H = 0.97 (methylene) and 0.98 (methine) Å, and N—H = 0.90 Å] and refined as riding with Uiso(H) = 1.2Ueq (C,N). H atoms of water molecules were found in a difference Fourier map and were refined with restrained geometrical parameters [O—H = 0.85 (2) Å, H···H = 1.38 (2) Å, and Uiso = 1.5Ueq(O)]. One H atom of one water molecule is disordered over two positions (H23/H24), which were refined with site occupancies of 0.5. Atom H26 of a water molecule was refined with a restrained geometrical parameter to form an ideal hydrogen bond [H26···O2v = 2.00 (5) Å; symmetry code: (v) -x + 1/2, y + 1/2, -z + 1]. One perchrolate anion is disordered over two positions (O7—O10 and O11—O14), which were refined with site occupancies of 0.5. Atoms O7, O8, O9 and O10, disordered on a twofold axis of the Cl2, were refined with site occupancies of 0.5.
Thiolato groups coordinated to a metal center possess relatively strong Lewis basicity, which allows them to bind with a second metal center (Konno, 2004). Previously, Konno et al. (2001) reported ΛL-[Co(L-cys-N,S)(en)2]+ (L-cys = L-cysteinate, en = ethylenediamine) reacts with AgNO3 to give an S-bridged (CoIIIAgI)n coordination polymer, {ΛL-[Ag{Co(L-cys-N,S)(en)2}](NO3)2}n.H2O (II). In this compound, the ΛL-[Co(L-cys-N,S)(en)2]+ unit binds with two AgI atoms through sulfur and with another AgI atom through a carboxylate group, to give a sheet-like structure. In this paper, we report on the structure of ΛLΛL-[Ag{Co(L-cys-N,S)(en)2}2](ClO4)3.5H2O (I), which was obtained by the 2:1 reaction of ΛL-[Co(L-cys-N,S)(en)2]+ with AgClO4.
The cation is composed of two octahedral [Co(L-cys-N,S)(en)2]+ units that are linked by an AgI atom through the S atoms to form a linear-type S-bridged CoIIIAgICoIII trinuclear structure in [Ag{Co(L-cys-N,S)(en)2}2]3+ (Fig. 1). The AgI atom, which is locate on a twofold axis, adopts an almost linear coordination geometry, unlike an angular geometry found in (II) (S—Ag—S = 149.62 (7) °). Furthermore, the Ag—S bonds in (I) are appreciably shorter than those in (II) (Ag—S = 2.501 (3), 2.511 (3) Å). These differences are ascribed to the fact that the AgI center in (II) is coordinated by a carboxylate group (Ag—O = 2.598 (1), 2.490 (8) Å), besides two thiolato groups. Other bond distances and angles in (I) are similar to those in (II) (Table 1). The two [Co(L-cys-N,S)(en)2]+ units in (I) have an Λ configuration because of the configuration of the mononuclear ΛL-[Co(L-cys-N,S)(en)2]+ reactant. The L-cys N,S-chelate ring adopts a λ conformation; the two en N,N-chelate rings adopt δ and λ conformations.
The cation is connected with to four adjacent cations through N–H···O hydrogen bonds between coordinated amine groups and non-coordinated carboxylate groups to give a sheet-like structure (Fig. 2). The sheets are further linked through the perchlorate anions and water molecules through hydrogen bonds.

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. |

Thiolato groups coordinated to a metal center possess relatively strong Lewis basicity, which allows them to bind with a second metal center (Konno, 2004). Previously, Konno et al. (2001) reported ΛL-[Co(L-cys-N,S)(en)2]+ (L-cys = L-cysteinate, en = ethylenediamine) reacts with AgNO3 to give an S-bridged (CoIIIAgI)n coordination polymer, {ΛL-[Ag{Co(L-cys-N,S)(en)2}](NO3)2}n.H2O (II). In this compound, the ΛL-[Co(L-cys-N,S)(en)2]+ unit binds with two AgI atoms through sulfur and with another AgI atom through a carboxylate group, to give a sheet-like structure. In this paper, we report on the structure of ΛLΛL-[Ag{Co(L-cys-N,S)(en)2}2](ClO4)3.5H2O (I), which was obtained by the 2:1 reaction of ΛL-[Co(L-cys-N,S)(en)2]+ with AgClO4.
The cation is composed of two octahedral [Co(L-cys-N,S)(en)2]+ units that are linked by an AgI atom through the S atoms to form a linear-type S-bridged CoIIIAgICoIII trinuclear structure in [Ag{Co(L-cys-N,S)(en)2}2]3+ (Fig. 1). The AgI atom, which is locate on a twofold axis, adopts an almost linear coordination geometry, unlike an angular geometry found in (II) (S—Ag—S = 149.62 (7) °). Furthermore, the Ag—S bonds in (I) are appreciably shorter than those in (II) (Ag—S = 2.501 (3), 2.511 (3) Å). These differences are ascribed to the fact that the AgI center in (II) is coordinated by a carboxylate group (Ag—O = 2.598 (1), 2.490 (8) Å), besides two thiolato groups. Other bond distances and angles in (I) are similar to those in (II) (Table 1). The two [Co(L-cys-N,S)(en)2]+ units in (I) have an Λ configuration because of the configuration of the mononuclear ΛL-[Co(L-cys-N,S)(en)2]+ reactant. The L-cys N,S-chelate ring adopts a λ conformation; the two en N,N-chelate rings adopt δ and λ conformations.
The cation is connected with to four adjacent cations through N–H···O hydrogen bonds between coordinated amine groups and non-coordinated carboxylate groups to give a sheet-like structure (Fig. 2). The sheets are further linked through the perchlorate anions and water molecules through hydrogen bonds.
