The present work is directed towards the study of the reactions of the dimethyl and diethyl dithiocarbamates of group 15 elements (P, As, and Sb) with the halides of group 12 metals MX2 (where M is Zn, Cd and Hg; X= Cl, Br and I). The reactions were conducted in dry conditions using a two-manifold vacuum line or glove box by transferring ligand solution to stirred solution of the metal halide in the appropriate organic solvent, under an atmosphere of dry oxygen-free argon. The results of the reactions of dialkyl dithiocarbamates of group 15 elements (P, As, Sb) with ZnX2, CdX2, and HgX2 is the isolation of ligand exchange complexes which have the general empirical formula: M(CS2NR2)2 or MX(CS2NR2) depending upon reaction molar ratio. (Where M= Zn, Cd, Hg; X= Cl, Br, I; R= Me or Et). The isolated ligand exchange-complexes were identified by the following methods: Elemental analysis for carbon, hydrogen and nitrogen. Determination of the meting points. 1H and 31P-NMR spectroscopy. Studying the full crystal structure, by x-ray diffractometer, for representative compounds; zinc (II) bis(diethyl dithiocarbamate) and cadmium (II) bis (diethyl dithiocarbamate
