Anionic halide and isothiocyanate adducts of zinc and cadmium dithiocarbamates
The mixed-ligand complexes [NEt4][Zn(S2CNMe2)2X] (X = Cl, Br, or NCS) and [NR4][Cd(S2CNEt2)2X] (R = Et, X = Cl, Br, or NCS; R = Bun, X = I) have been prepared by reaction of zinc and cadmium bis(dithiocarbamate) with the tetraalkylammonium salt of the halide or thiocyanate in acetone at room tempera...
