| Abstract Complexes of the type [Cu(B`SCH)(LH)]CO3 and [Cu(B`SC)(L)] have been prepared in neutral and basic medium, respectively {where B`SCH= benzoin semicarbazone, B`SC=deprotonated B`SCH ligand, AH= one of the substituted salicylic acid : salicylic acid (A1H), 2-acetylsalicylic acid (A2H), 3,5-dinitrosalicylic acid (A3H), 5-aminosalicylic acid (A4H) or 5-sulphosalicylic acid (A5H), A= deprotonated AH ligand}. The resulted complexes have been characterized physico-chemically. The effect of gamma rays have been studied on these complexes under conditions where the hydroxyl radicals were scavenged by sodium formate solution and in presence of nitrogen gas. The electronic spectral data and molar conductivities indicated that copper (II) ion may be reduced to copper (I) and presence of charge transfer between the metal ion and the ligands in some complexes. In addition some complexes have been completely decomposed and some of them polymerized while the others did not affected during the selected time of irradiation. | ||
