Synthesis and Characterization of Some Cinnamaldehyde Schiff Base Complexes

Metal complexes of the general formula [M(L)2]X {where M is Cr(III) and Fe(III) and L, N- (cinnamalidene) leucine or N- (cinnamalidene) phenylalanine is a Schiff base formed by condensation of cinnamaldehyde (Cinn) with amino acid, L-Leucine (Leu) or L-Phenylalanine (Phe); X = Cl- or NO3-}, have been prepared and characterized by analytical, spectral, magnetic and conductance measurements. IR spectra showed that the nitrogen of the azomethine group, carbonyl oxygen and the negatively charged oxygen atoms of the amino acid take part in cardination. Magnetic measurements and electronic spectral studies suggested an octahedral structures for all complexes. Conductance measurements showed a 1:1 electrolytic nature of the complexes.
