Complexes of Mn(II), Fe(III), Co(II), Ni(II), Cu(II), Zn(II) and UO2(VI) with N-(4-formylantipyrine)benzothiazole-2-ylacetohydrazide (HL) have been prepared in ethanolic solution and characterized by physical and spectral methods. IR, electronic, and ESR spectra of the complexes, as well as IR, 1H NMR, and FAB-MAS spectra of the ligand have been obtained. The IR spectra show that the ligand behaves as a monobasic tridentate ligand and coordination takes place via the azomethine nitrogen, enolic oxygen of the hydrazide moiety and the carbonyl oxygen of the pyrazolone ring. Stereochemistries are proposed for the complexes on the basis of spectral and magnetic studies. Also, the ligand and their metal complexes posses antifungal activity.
