Synthesis and Characterization of the New Fac-and Mer-[M (Caf)₃(SCN)₃],OH₂ by El Amane M*, El Hamdani M, Bouhdada M and Kennouche Y in Significances of Bioengineering & Biosciences

New fac-and mer-[M(caf)₃(SCN)₃]OH₂ caffeine complexes where caf = caffeine, SCN= thiocyanato and M= Cr(III), Fe(III) and Ru(III) were synthesized in simple reactions of chloride MCl₃, H₂O ; M= Cr(III), Fe(III) and Ru(III) with potassium thiocyanate in ethanol solution. The infrared and electronic spectral data of the complexes [M(caf)₃(SCN)₃]OH₂ suggest that the caffeine is coordinate through the nitrogen N9 and the thiocyanato behave a monodentate legend with sulphur atom donor towards metal ions. On the basis of the spectral data, the FT-IR, UV-Visible and EPR suggested the mer- and fac-octahedral complexes.
