| Abstract | ||
| Copper (II) complexes with mixed ligands : benzIl bis(semicarbazone)- BSCH2 and substituted salicylic acid (salicylic acid - A1H or 2-acetylsalicylic acid - A2H or 3,5-dinitrosalicylic acid - A3H or 5-aminosalicylic acid - A4H or 5-sulphosalicylic acid - A5H ) have been prepared and characterized by physical and chemical methods . Complexes of the type [Cu(BSCH2)(AH)](NO3)2 and [Cu(BSCH)(A)] (where AH = A1H or A2H or A3H or A4H or A5H, A = deprotonated AH ligand and BSCH = deprotonated BSCH2 ligand) have been proposed in neutral and basic medium, respectively. Under conditions where hydroxyl radicals scavenged by formate (in presence of nitrogen gas), the results observed indicated that a reduction process involving copper ion may occurred. Moreover, the so formed CO2.- under these conditions reduced Cu(II) to Cu(I) . The conductivity and electronic spectral measurements were in a good agreement with the above . The conclusion depending on our results, concerning the existance of charge transfer between metal and ligand in the complexes. | ||
