SYNTHETIC AND BIOCHEMICAL-STUDIES OF SOME HYDRAZINE CARBODITHIOIC ACID-DERIVATIVES OF DIOXOMOLYBDENUM(VI)

Some biologically active thioimines, formed by the condensation of het erocyclic 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 mo nofunctional bidentate thioimines. The complexes have been characteris ed on the basis of elemental analyses, molecular weight determinations , X-ray powder diffraction, IR, H-1 NMR and C-13 NMR spectral studies and an octahedral geometry has been proposed. The ligands and their me tal complexes have been tested against a number of pathogenic fungi an d bacteria at different concentrations and are found to possess suffic ient fungicidal and bactericidal properties.
