  Mercury(II) complexes of pyrrolidinedithiocarbamate (PDTC) having the general formula [Hg(PDTC)X] (X = Cl-, SCN-, and CN-) and [Hg(PDTC)2] have been prepared and characterized by elemental analysis, IR, and NMR. The crystal structure of [Hg(PDTC)2] has also been determined by X-ray crystallography, showing that the complex is a centrosymmetric dimer, [Hg2(PDTC)4] (bis[µ2-(pyrrolidinedithiocarbamato-S,S')(pyrrolidinedithiocarbamato-S,S')mercury(II)]) (1). The solid-state structure of 1 contains two crystallographically equivalent Hg(II) centers in a distorted tetrahedron.
