Synthesis and study of some mixed ligand complexes of caffeine, y-picoline and thiocyanate with some metal ions

الملخص EN

This paper presents the preparation and study of some mixed ligand complexes of caffeine, y-picoline and thiocyanete ions with some metal ions.

The reaction was carried out in (1:1) ethanol: water mixture using the appropriate molar ratio of metal: ligand (1:1:1:2) as required.

The resulting products were found to be solid crystalline complexes which have been characterized by using I.R, U.V-Visible spectra, elemental analysis, thermal stability, molar conductivity and magnetic properties.

The general formula of the prepared complexes given [M (CA)( y-pico)X2] was suggested as.

Where M2+ = V02+, Co2\ Ni2+, Cu2+, Zn2+, Cd2+O ^3 CA= Caffeine (C8H10O2 N4) y-pico= y-picoline (C6H7N) X=Thiocyanate ion (SCN ).
