A NEW CYCLOBUTANE SUBSTITUTED SCHIFF BASE LIGAND, SYNTHESIS OF ITS Cd(II), Co(II), Cu(II), Ni(II) AND Zn(II) COMPLEXES AND INVESTIGATION OF THEIR STRUCTURE

摘要

A new, thiazole derivative ligand, 4-(1-phenyl-1-methylcyclobutane-3-yl)-2-(2-hydroxy-5-bromo benzylidenehydrazino) thiazole (LH), has been synthesized by the reaction of 2-ydroxy-5-bromobenzaldehyde, thiosemicarbazide and subsequently 1-phenyl-1-methyl-3-(2-chloro-1-oxoethyl) cyclobutane. Mononuclear complexes with a metal-ligand ratio of 1:2 have been prepared with Cd(II), Co(II), Cu(II), Ni(II) and Zn(II). The authenticity of the ligand and its complexes was established by elemental analyses, IR, ~(13)C and ~1H NMR spectra, magnetic susceptibility measurements and thermogravimetric analyses (TGA) and differential scanning calorimetry (DSC).
