Synthesis And Characterization Of 1 4- Dihydroquinoxaline-23-dione Derivativesbased Co (ii) And Ni (ii) Complexes

In recent years, there has been enhanced interest in the synthesis and characterizationrnof transition metal complexes containing Schiff bases as ligands due to theirrnimportance. According to this concept, two Schiff base complexes, [CoL2Cl2] andrn[NiL2]Cl2 were synthesized based on the Schiff base ligand that was a result ofrncondensation of 1, 4-dihydroquinoxaline-2, 3-dione and 3-hydroquinoxaline-2(1H)-rnone. In the process of formation of the ligand and complexes, chemicals like OPD,rndiethyl oxalate, hydrazine, ethylenediamine, Co (II) and Ni (II) chloride salts, andrnsolvents such as diethyl ether, methanol, butanol, were used. The synthesized ligandrnand complexes were characterized using IR, UV-Vis., molar conductivity, AAS, andrnother physical measurements such as melting point and solubility were determined.rnBased on the physico-chemical analysis, octahedral structure of Co (II) complex andrnsquare planar structure of Ni (II) complex were proposed.
