Indian Association for the Cultivation of Science, Calcutta-32. Department of Pure Chemistry, University College of Science, Calcutta-9. Manuscript received 15 February 1972; revised 20 September 1973; accepted 23 September 1974 Thiosemicarbazone of pyruvic acid has been used as a coordinating ligand. The complex compounds of the ligand with Cu(Il), Ni(ll), Mn(Il), Co(II), Fe(III), Zn(ll) and Cd(ll) have been isolated In the soild state and characterised on the basis of elemental analyses, magnetic susceptibility values as well as from electronic and vibrational spectral data
