Mixed ligand complexes of VO(IV) and ZrO(IV) with pyrrole-2- carboxaldehyde thiosemicarbazone (PCTS) as primary and salicylaldehyde as secondary ligand have been synthesized and characterized on the basis of analytical, magnetic and spectral studies. Analytical data proposed l:l:l (M-L-L') stoichiometric composition for the synthesized complexes [where M= VO(IV)/ ZrO(IV), L=PCTS and L'H= salicylaldehyde]. Electronic spectra of VO(IV) complexes suggested distorted octahedral geometry for them. IR spectra of the ligands and complexes showed bidentate nature of the ligands. The complexes are non -electrolytes. ZrO(IV) complexes possess hepta coordinated structure.
