Abstract/Summary A new symmetrical vicinal dioxime, N,N′-bis-{4-[[(2-hydroxyphenyl)methylene]hydrazinecarbonyl]phenyl}diaminoglyoxime (LH4), was prepared by reacting anti-dichloroglyoxime with salicylaldehyde 4-aminobenzoylhydrazone. The reaction of ligand with Ni2+ salts gave mono-and homopentanuclear complexes, [Ni(LH3)2] and [Ni5(LH)2X2]. Furthermore, heteropentanuclear complexes of dioxime ligand, [Cu4Ni(LH)2X4], were prepared by the reaction of [Ni(LH3)2)] with Cu2+ salt and a monodentate ligand (X = SCN−, CN−, or N 3 − ). The structures of both the new symmetrical vicinal dioxime and its complexes were identified by elemental analyses, IR, 1H NMR, UV-VIS spectra, and magnetic susceptibility. The elemental analyses and spectral data indicate that the hydrazone side of ligand acts as a O,N,O′ tridentate and the fourth position is occupied with monodentate anion such as SCN−, CN−, N 3 − .
