Synthetic and biochemical studies of some hydrazine carbodithioic acid derivatives of dioxomolybdenum (VI)

Abstract

Some biologically active thioimines, formed by the condensation of heterocyclic aldehydes and ketones with phenylmethyl ester derivative of hydrazine carbodithioic acid and their dioxomolybdenum (VI) complexes have been described. The monomeric complexes are formed by the bimolar reactions of dioxobis(2,4-pentanedionato-O,O´)molybdenum (VI) with monofunctional bidentate thioimines. The complexes have been characterised on the basis of elemental analyses, molecular weight determinations, X-ray powder diffraction, IR, ¹H NMR and ¹³C NMR spectral studies and an octahedral geometry has been proposed. The ligands and their metal complexes have been tested against a number of pathogenic fungi and bacteria at different concentrations and are found to possess sufficient fungicidal and bactericidal properties.
