| Abstract | ||
| Complexes of the type [Cu(B`SCH)(AH)](NO3)2 and [Cu(B`SC)(A)] have been prepared in neutral and basic mediam, respectively, (where AH= substituted salicylic acid: salicylic acid-SA and o-acetylsalicylic acid-OASA and 3,5-dinitrosalicylic acid-DNSA or 5-aminosalicylic acid-ASA or 5-sulphosalicylic acid-SSA; A=deprotonated form of the AH ligand; B`SCH=benzoin semicarbazone; B`SC=deprotonated form of the ligand B`SCH).The prepared complexes were characterized by copper ion determination, relative molecular weight determination, magnetic and molar conductance measurements, infrared and electronic spectral data. The effect of γ-rays have been studied on the aqueous solutions of the complexes under conditions where the hydroxyl radicals were scavenged by 10-3 M sodium formate in presence of dinitrogen gas at room temperature (25 ± 2 oC). Results indicated that copper (II) was reduced to copper (I) and a charge transfer between metal ion and ligands in some complexes were noticed. Some complexes have been completely decomposed while others did not affect by the radiolysis. | ||
