Description
Summary:Complexes of Mn(II), Fe(III), Co(II), Ni(II), Cu(II), Zn(II) and UO 2 (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, 1 H 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.
