| Abstract | ||
| The synthesis of some new complexes was performed by the reaction of uranyl salts with three ligands of Schiff base. The ligands were obtained by the condensation of benzoin with benzoyl hydrazide (DBEH2), salicyloyl hydrazide (DSEH2) and p-nitrobenzoylhydrazide (DPEH2). The complexes of the general formula [UO2(LH2)2]X2 and [(UO2)2L2] (where LH2 and L=are neutral and dibasic form of the three ligands, X=NO3 or CH3COO ions) for those formed by the reaction of uranyl salts and the ligands in neutral and basic medium, respectively. All the complexes were characterized by using elemental microanalysis, molar conductances, infrared, electronic and 1HNMR spectra. These studies revealed octacoordinate of uranium atom for complexes formed in neutral medium and dinuclear hexacoordinate complexes formed in basic medium. | ||
