dc.description.abstractCoordination compounds play vital roles in biology, biochemistry and medicine, controlling the structure and function of many enzymes and their metabolism. They find varied application in many industrial processes and in the development of new materials with specifically designed properties. Thus, synthesis and study of the complexes is very important. In this work, equimolar quantities of o-phenylene diamine and oxalic acid were ground with pestle in a mortar to produce 1,4-dihydroquinoxaline 2,3-dione, which behaves as a bidentate O,N donor ligand by solvent free method. The new ligand 3-(2-hydroxy-phenylalanine) qunioxaline-2-one was synthesized by mixed equimolar ratio of 1,4-dihydro-quinoxaline-2,3-dione with 2- amonphenol by conventional method. Zn (II) and Cd (II) complexes were synthesized from mixed the ligand 1,4-dihydro-quinoxaline-2,3-dione derivative ligand with salts of anhydrous Zn(II) nitrate and anhydrous Cd(II) chloride by template method. These complexes and ligand have been characterized with the help of various spectra technique, such as AAS, IR, UV/VIS spectroscopic techniques as well as molar conductance, chloride test and melting point measurements have been done as supports to conclude the structures of the complexes. The square planer geometry was proposed for Zn-L complex and tetrahedron geometry was proposed for Cd-L complex.en_US
