Synthesis and characterization of copper(II), nickel(II) and cobalt(II) complexes with a new schiff base derivative of isonicotinic acid hydrazide

Abstract

A series of binuclear complexes of the type |M(HDCTH)(H₂O)₂|₂X₂ [where HDCTH = a schiff base derived from the condensation of isonicotinic acid hydrazide (INH) and diacetylmonoxime (DM), [M =CO^ll, Ni^ll and Cu^ll, and X = CI^- , Br^-, NO<img src='/image/spc_char/3_bar.gif' border=0>] have been prepared and characterised by elemental analyses, magnetic measurements, electronic and IR spectral analyses. Infra red spectra of the complexes indicate the participation of azomethine nitrogen, oxime oxygen and carbonyl oxygen. The water molecules are coordinated as evidenced from the IR and thermal analyses. The magnetic and reflectance spectra suggest an approximately octahedral symmetry around the metal ions.
