Tetraethylammonium bis(N,N-diethyldithiocarbamato-kappa2S,S')iodocadmate(II)

The title compound, (C8H20N)[Cd(C5H10NS2)2I], containing a heteroleptic five-coordinate mononuclear anionic cadmium complex, crystallizes in orthorhombic form in the space group Pnma. Both anion and cation lie about mirror planes. Unlike other known [Cd(dtc)2X]-type complexes (where dtc is dithiocarbamate and X is a halogen or pseudohalogen), the central CdS4I core shows a square-pyramidal configuration, with a basal plane defined by four S atoms from two chelating dithiocarbamate ligands related by a symmetry plane. The central Cd atom is displaced from the basal S4 plane towards the apical I atom of the square pyramid.
