ABSTRACT:

The reaction between phenylalanine and oxalylchloride/malonylchloride results in new quadridentate ligands. bis-[1-phenyl-2-carboxy-2-ethyl)-oxamide [PCEOA], bis(1-phenyl-2-carboxy-2-ethyl) malonamide [PCEMA]. These ligands form 1:1 complexes of general formula [M(L)(H2O)2]Cl, [M(L)]H2O, M[(L)], [M(L)]2H2O, L=PCEOA and PCEMA. M= FeIII, CoII, NiII, CuII and ZnII. The organic compounds containing amide group play an important role in biology, as it constitutes the repeating unit of the polypeptide macro molecules. Further they have allocated the attention of co-ordination chemists as they serve as model for metal-peptide interactions and to metalloenzymes1. In the present paper, the preparation and characterization of two new ligands bis-[1-phenyl-2-carboxyl-2-ethyl] oxamide [PCEOA] and bis-[1-phenyl-2-carboxyl-2-ethyl] malonamide [PCEMA] and their complexes with FeIII, CoII, NiII, CuII and ZnII are described.
