The dinuclear title compound, [Zn2(C3H6NS2)4(C12H10N2)], features two five-coordinate Zn atoms, one with an NS4 coordination geometry distorted towards a trigonal-bipyramidal arrangement, and the other distorted towards a square pyramid. In the crystal, molecules are connected into supramolecular zigzag chains via C—H⋯S contacts. Chains are connected via C—H⋯π interactions, consolidating the crystal packing.

Compound (I) was prepared by following a standard literature procedure (Lai & Tiekink, 2003). and recrystallized from the slow evaporation of a chloroform/acetonitrile (3:1) solution of (I); m. pt. 555–557 K.
The H atoms were geometrically placed (C—H = 0.95–0.98 Å) and refined as riding with Uiso(H) = 1.2–1.5Ueq(C). The maximum and minimum residual electron density peaks of 1.51 and 0.73 e Å-3, respectively, were located 1.81 Å and 1.17 Å from the S5 and Zn2 atoms, respectively.
Compared to their τ = 0.58 and 0.39, respectively, compared with the ideal values of 0.0 and 1.0 for SP and TP, respectively (Addison et al., 1984).
(-S2COR) and dithiophosphates [-S2P(OR)2], crystal engineering studies of zinc(II) dithiocarbamates (-S2CNR2) are less well developed (Lai et al., 2002; Chen et al., 2006; Benson et al. 2007). This is likely due to the stronger chelating ability of the dithiocarbamate ligand which tends to preclude incorporation of multiple bridging ligands within the Zn atom coordination sphere. This principle is exemplified in the title compound, (I), Fig. 1, where each Zn atom is five coordinate within a NS4 donor set. The dithiocarbamate ligands are chelating but form disparate Zn—S bond distances ranging from 2.3204 (15) to 2.6650 (16) Å. The coordination geometries for the Zn1 and Zn2 atoms are distorted towards trigonal bipyramidal (TP) and square pyramidal (SP), respectively. This is quantified by the values ofThe 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). Here, the range of Zn—S bond distances was considerably narrower, i.e. 2.4100 (10) to 2.4914 (11) Å, and the coordination geometry was close to SP (τ = 0.13).
Molecules of (I) are connected by C—H···S interactions, Table 1, to form supramolecular zigzag chains that pack in the ab plane, Table 1 and Fig. 2. Chains are connected via C—H···π interactions to consolidate the crystal packing, Table 1 and Fig. 3.

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. |

Compared to their xanthates (-S2COR) and dithiophosphates [-S2P(OR)2], crystal engineering studies of zinc(II) dithiocarbamates (-S2CNR2) are less well developed (Lai et al., 2002; Chen et al., 2006; Benson et al. 2007). This is likely due to the stronger chelating ability of the dithiocarbamate ligand which tends to preclude incorporation of multiple bridging ligands within the Zn atom coordination sphere. This principle is exemplified in the title compound, (I), Fig. 1, where each Zn atom is five coordinate within a NS4 donor set. The dithiocarbamate ligands are chelating but form disparate Zn—S bond distances ranging from 2.3204 (15) to 2.6650 (16) Å. The coordination geometries for the Zn1 and Zn2 atoms are distorted towards trigonal bipyramidal (TP) and square pyramidal (SP), respectively. This is quantified by the values of τ = 0.58 and 0.39, respectively, compared with the ideal values of 0.0 and 1.0 for SP and TP, 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). Here, the range of Zn—S bond distances was considerably narrower, i.e. 2.4100 (10) to 2.4914 (11) Å, and the coordination geometry was close to SP (τ = 0.13).
Molecules of (I) are connected by C—H···S interactions, Table 1, to form supramolecular zigzag chains that pack in the ab plane, Table 1 and Fig. 2. Chains are connected via C—H···π interactions to consolidate the crystal packing, Table 1 and Fig. 3.
