Synthesis, Characterization and Properties of Heterobimetallic Complexes of Zinc(II) Dithiocarbamate Derivatives with Cobalt, Nickel and Copper metal Ions

Abstract

Several heterobimetallic complexes of the general formula
[Zn (R-dtc)₂·MCI₂]_n, where R-dtc is methyl-, cycloheptyl- or
dicyclohexyl-dithiocarbamate, M==Co, Ni, Cu and n = 1 or 2, have
been prepared from the reaction of the presursor compound Zn(R-dtc)₂
(prepared from Zinc(II) salt and the sodium or potassium
dithiocarbamate derivative) and the corresponding anhydrous metal
salt MCl₂ in non-aqueous solvents and in different molar ratios.
The complexs have been characterized physicochemically and spectroscopically.
Suggested structures for the complexes have been
given and discussed.
