The dinuclear title solvate, [Zn2(C5H10NS2)4(C12H10N2)]·CHCl3, features two five-coordinate Zn atoms; both coordination polyhedra are distorted, but one has an NS4 donor set approximating to a square pyramid (with the N atom in the apical site), while the other is closer to a ZnNS4 trigonal-bipyramidal arrangement (with the N atom in an equatorial site). In both cases, the ZnII atom is chelated by two S,S′-bidentate dithiolate ligands. In the crystal, the chloroform solvent molecules reside in cavities defined by the dinuclear species and are held in place via C—H⋯S contacts.

Compound (I) was prepared by following a standard literature procedure (Lai & Tiekink, 2003) whereby two equivalents of Zn(S2CNEt2)2 were added to trans-1,2-bis(4-pyridyl)ethylene. Crystals were obtained from slow evaporation of a chloroform solution. When heated, the crystals turned opaque at 349–351 K and melted at 401–403 K.
The H atoms were geometrically placed (C—H = 0.95–0.99 Å) and refined as riding with Uiso(H) = 1.2–1.5Ueq(C).
The title compound (I) was prepared in connection with crystal engineering studies of zinc(II) 1,1-dithiolates (Lai et al., 2002; Chen et al., 2006; Benson et al. 2007). The dinuclear compound features two five coordinate Zn atoms, each being coordinated by two dithiocarbamate ligands and a pyridine-N atom. The dithiocarbamate ligands are chelating but form disparate Zn—S bond distances that range from 2.3381 (10) to 2.6575 (9) Å. The coordination geometries for the Zn1 and Zn2 atoms are each based on a NS4 donor set but are distinct. Thus, the geometries for the Zn1 and Zn2 atoms are distorted towards trigonal bipyramidal (TB) and square pyramidal (SP), respectively. This is quantified by the values of τ = 0.56 and 0.36, respectively, compared with the ideal values of 1.0 and 0.0 for TB and SP, respectively (Addison et al., 1984).
The most closely related structure available for comparison is the diethyldithiocarbamate analogue of (I) which was co-crystallized with a trans-1,2-bis(4-pyridyl)ethylene molecule (Lai & Tiekink, 2003) rather than a solvent chloroform molecule as for (I). In the former, the range of Zn—S bond distances was considerably narrower, i.e. 2.4100 (10) to 2.4914 (11) Å, and the coordination geometry for Zn (the dinuclear molecule is centrosymmetric) was close to SP (τ = 0.13).
The solvent chlorofrom molecules in (I) reside in cavities defined by the dinuclear molecules and are held in place by C—H···S interactions, Table 1,

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. |

The title compound (I) was prepared in connection with crystal engineering studies of zinc(II) 1,1-dithiolates (Lai et al., 2002; Chen et al., 2006; Benson et al. 2007). The dinuclear compound features two five coordinate Zn atoms, each being coordinated by two dithiocarbamate ligands and a pyridine-N atom. The dithiocarbamate ligands are chelating but form disparate Zn—S bond distances that range from 2.3381 (10) to 2.6575 (9) Å. The coordination geometries for the Zn1 and Zn2 atoms are each based on a NS4 donor set but are distinct. Thus, the geometries for the Zn1 and Zn2 atoms are distorted towards trigonal bipyramidal (TB) and square pyramidal (SP), respectively. This is quantified by the values of τ = 0.56 and 0.36, respectively, compared with the ideal values of 1.0 and 0.0 for TB and SP, respectively (Addison et al., 1984).
The most closely related structure available for comparison is the diethyldithiocarbamate analogue of (I) which was co-crystallized with a trans-1,2-bis(4-pyridyl)ethylene molecule (Lai & Tiekink, 2003) rather than a solvent chloroform molecule as for (I). In the former, the range of Zn—S bond distances was considerably narrower, i.e. 2.4100 (10) to 2.4914 (11) Å, and the coordination geometry for Zn (the dinuclear molecule is centrosymmetric) was close to SP (τ = 0.13).
The solvent chlorofrom molecules in (I) reside in cavities defined by the dinuclear molecules and are held in place by C—H···S interactions, Table 1,
