ABSTRACT
Complexes of Mn(II), Fe(III), Co(II), Ni(II), Cu(II), Zn(II) and UO2(VI) with N-(2-furylidene)benzothiazole-2-ylacetohydrazide (HL) have been prepared in ethanolic solution and characterized by physical and spectral methods. IR, electronic, TGA and ESR spectra of the complexes, as well as IR, 1H NMR spectra of the ligand have been obtained. IR spectra show that the ligand coordinates either as neutral bidentate via the azomethine nitrogen and carbonyl oxygen or as a monobasic tridentate ligand via the enolic oxygen, azomethine nitrogen and furane ring oxygen. Stereochemistries are proposed for the complexes on the basis of spectral and magnetic studies.
