Palladium (II) complexes of type [Pd(L)Cl-2] [where, L= benzyl-N-thiohydrazide (L-1), (benzyl-N-thio)-1,3-propanediamine (L-2), benzaldehyde benzyl-N-thiohydrazone (L-3) and salicylaldehyde-benzyl-N-thiohydrazone (L-4)] have been synthesized. The thiohydrazides, thiodiamine and thiohydrazones can exist as thione-thiol tautomer and coordinate as as a bidentate N-S ligand. The ligands were found to act in monobasic bidentate fashion. The complexes have been characterized by elemental analysis, IR, mass, electronic and H-1 NMR spectroscopic studies.
