Abstract

The present work describes the studies the studies on the coordination behavior of 4[N-(benzalidene0 amino] antipyrinesemicarbazone (BAAPS) (I), 4[N-(furfural)amino] antipyrinesemicarbazone (CAAPS) (III) in presence of dimethyl sulfoxide (DMSO) or diphenylsulfoxide (DPSO) towards Th4+ and UO22+ salts. All the complexes were isolated in non-aqueous solvent like ethanol or acetone. The mixed ligand complexes have the general composition ThX4(L)DPSO ( X = Cl, Br, I, NCS or NO3 or CH3COO) and UO2(CIO4)2(L)2DMSO (L=FFAAPS or CAAPS). The analytical data include element analyses, molecular weight determination, conductivity, spectral and thermal studies. XRD-powder diffraction of two representative thorium(IV) complexes have also been reported. In these complexes, the primary ligands behave as neutral tridentate (N,N,O) ligand, while the secondary ligand (DMSO or DPSO) acts as unidentate oxygen donor. Thorium(IV) displays coordination number 6,7,8 or 12, while uranium(VI) ion displays coordination number 8,9 or 10 depending on the nature of anionic ligand.
