Abstract

This work presents preparation and study of a new mixed ligand complexes of caffeine and cyanate ion with Co(II), Ni(II),Cu(II), Zn(II) and Cd(II). The prepared complexes were characterized on the bases of their elemental analysis(C, H, N), metal percentage determination, IR and UV-Vis spectroscopy. Conductivity measurements as well as their magnetic moments were carried out. From the obtained information the general formula has been given for the prepared complexes [M(CA)4Y2] where CA=caffeine, Y=cyanate ion and M=Co(II), Ni(II),Cu(II), Zn(II) and Cd(II).
