co-ordination geometry with the thiocyanate N atom occupying an equatorial position and the dithiocarbamate ligands spanning one axial and one equatorial position each. The infrared and Raman spectra (2100–50 cm–1) of the complexes are discussed. The metal–sulfur stretching frequencies are assigned in the ranges 226–205 (Zn–S) and 203–145 cm–1(Cd–S), respectively.
