✦ Synopsis


A new 1,4-piperazine-bis-dithiocarbamate sodium salt and its metal complexes have been prepared and characterized by elemental analyses, conductivity measurements, magnetic susceptibilities, thermal analyses (TG and DTG) and spectroscopic (i.r., electronic and EPR) techniques. The ligand is tetrasulphur coordinated to the metals in polymeric structures. The magnetic measurements are indicative of one unpaired electron in the copper(I1) complex; a p value typical of planar low-spin complexes has been obtained in the case of the cobalt(H) derivative,while a distortion from the planarity is suggested in the case of the nickel(I1) complex. Tentative structures of the complexes are proposed on the basis of the obtained results.
