The dinuclear title compound, [Zn2(C7H14NS2)4(C12H10N2)], is centrosymmetric about the central C=C bond. The five-coordinate Zn atom is bonded to two asymmetrically chelating dithiocarbamate ligands and a pyridine N atom to define an NS4 coordination geometry tending towards a square pyramid, with the N atom in the apical site. In the C—H⋯S contacts lead to supramolecular chains.

Compound (I) was prepared by following a standard literature procedure (Lai & Tiekink, 2003) whereby two equivalents of Zn(S2CN(iPr)2)2 were added to trans-1,2-bis(4-pyridyl)ethylene. Golden blocks of (I) were obtained from the slow evaporation of a chloroform/acetonitrile solution (3/1) of (I); m. pt. 513–515 K.
The H atoms were geometrically placed (C—H = 0.95–1.00 Å) and refined as riding with Uiso(H) = 1.2–1.5Ueq(C).
Crystal engineering studies of zinc(II) 1,1-dithiolates (Lai et al., 2002; Chen et al., 2006; Benson et al. 2007) motivated the synthesis of the title compound (I). The dinuclear compound is centrosymmetric and features a five coordinate Zn atom. Two asymmetrically chelating dithiocarbamate ligands (range of Zn–S = 2.3655 (7) to 2.5720 (7) Å) and a pyridine-N atom (Zn–N 2.0621 (18) Å) define a NS4 donor set. The coordination geometry is distorted towards square pyramidal (SP). This is quantified by the value of τ = 1/3, which compares with the ideal values of 0.0 and 1.0 for SP and TB, respectively (Addison et al., 1984).
In the π contacts where the π-system is defined by the ZnS2C chelate ring containing the S3 atom [C13—H13a···Cg = 2.86 Å, C13···Cg = 3.630 (3) Å with an angle of 136° at the H13a atom for 1 - x, 1 - y, -z].
C—H···S contacts link molecules into a supramolecular chain, Table 1 and Fig. 2. Chains are linked into a 2-D array via C—H···For background to supramolecular polymers of zinc 1,1-dithiolates, see: Lai et al. (2002); Chen et al. (2006); Benson et al. (2007).

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. |

Crystal engineering studies of zinc(II) 1,1-dithiolates (Lai et al., 2002; Chen et al., 2006; Benson et al. 2007) motivated the synthesis of the title compound (I). The dinuclear compound is centrosymmetric and features a five coordinate Zn atom. Two asymmetrically chelating dithiocarbamate ligands (range of Zn–S = 2.3655 (7) to 2.5720 (7) Å) and a pyridine-N atom (Zn–N 2.0621 (18) Å) define a NS4 donor set. The coordination geometry is distorted towards square pyramidal (SP). This is quantified by the value of τ = 1/3, which compares with the ideal values of 0.0 and 1.0 for SP and TB, respectively (Addison et al., 1984).
In the crystal structure, C—H···S contacts link molecules into a supramolecular chain, Table 1 and Fig. 2. Chains are linked into a 2-D array via C—H···π contacts where the π-system is defined by the ZnS2C chelate ring containing the S3 atom [C13—H13a···Cg = 2.86 Å, C13···Cg = 3.630 (3) Å with an angle of 136° at the H13a atom for symmetry operation 1 - x, 1 - y, -z].
