Abstract

Abstract The substitution reactions of heterocyclic thiosemicarbazones with triphenyllead(IV) chloride in 1:1 molar ratio give Ph3PbL (L = anion of thiosemicarbazone derived from heterocyclic aldehyde or ketone) type of complexes. The elemental analyses, molecular weight determinations, conductivity measurements and spectral (IR, 1H and 13C NMR) studies have been used to elucidate their penta-coordinated structures. Some representative ligands and their metal chelates have also been screened for their antimicrobial effects against different species of pathogenic fungi and bacteria.
