Abstract

New mixed ligand complexes were prepared by adding an ethanolic solution of 6-aminopurine to an aqueous solution of metal salts. This is followed by adding an ethanolic solution of theophylline and thiocyanate ion to give complexes with general formula [M (Tp)2 (Ad)X2] where Ad = 6-aminopurine, Tp = theophylline, X = thiocyanate ion and M = Co(II), Ni(II), Cu(II), Zn(II) and Cd(II). The resulting products were found to be crystalline which have characterized using UV-Visible spectroscopic properties and Infrared spectra. Elemental analyses were performed using (C, H, N) and atomic absorption technique. The magnetic susceptibility and the conductivity were also measured. The present results suggested that the adenine as bidentate is coordinated with metal ions through the two nitrogen atoms N3 and N9. The theophylline as monodentat is coordinated with metal ions through the nitrogen atom N9. Thiocyanate ions are coordinated through the sulfur atom.
