Bis(μ-N,N-di­allyl­dithio­carbamato)bis[(N,N-di­allyl­dithio­carbamato)cadmium]

The title compound, [Cd(2)(C(7)H(10)NS(2))(4)], is a neutral dinuclear cadmium(II) complex bearing four bis N,N-di­allyl­di­thio­carbamate ligands coordinating to two Cd(II) cations. In each of the monomeric subunits, there are four S atoms of two di­thio­carbamate ligands [Cd—S = 2.5558 (3), 2.8016 (3), 2.6050 (3) and 2.5709 (3) Å] that coordinate to one Cd(II) atom in a bidentate mode. The dimers are located over an inversion centre bridged by two additional bridging Cd—S bonds [2.6021 (3) Å], leading to a substantial distortion of the geometry of the monomeric subunit from the expected square-planar geometry. The five-coordinate environment around each of the Cd(II) ions in the dimer is best described as substanti­ally tetra­gonally distorted square pyramidal. The di­thio­carbamate groups are themselves planar and are also coplanar with the Cd(II) ions. The negative charge on these groups is delocalized by resonance across the S atoms bound to the Cd(II) cation. This delocalization of the π electrons in the di­thio­carbamate groups also extends to the C—N bonds as they reveal significant double bond character [C—N = 1.3213 (16) and 1.3333 (15) Å].
