SYNTHESIS, SPECTROSCOPIC CHARACTERIZATION, AND BIOLOGICAL ACTIVITY OF N-ISONICOTINOYL- N′-THIOBENZOYLHYDRAZINE COMPLEXES OF Co(II), Ni(II), Cu(II), AND Zn(II)
摘要:
A new ligand, N-isonicotinoyl-N'-thiobenzoylhydrazine (HINTB), has been prepared by the reaction of isonicotinic acid hydrazide and carboxymethyl dithiobenzoate. The addition complexes [M(HINTB)(2)Cl-2] [M = Co(II), Ni(II), Zn(II)], [Cu(HINTB)Cl-2], M(HINTB)(2)(CH3COO)(2) [M = Co(II), Ni(II)] and deprotonated complexes [Cu(INTB)(CH3COO)] and [Zn(INTB)(2)] have been prepared and characterized by elemental analyses, magnetic susceptibility, electronic, NMR and IR spectral data. The room temperature ESR spectra of [Cu(HINTB)Cl-2] [Cu(INTB)(CH3COO)] are characteristic of monomeric and dimeric species, respectively. The ligand and the complexes have been screened for activity against a number of fungi and bacteria.
