Studies on High Coordination Complexes of Thorium (IV) and Dioxouranium(Vl) with Phenyl Vinyl Sulfoxide

Abstract

Abstract A new series of ten complexes of thorium(iv) and dioxouranium(Vl) with phenyl vinyl sulfoxide (PVSO) having general composition ThX4. n(PVSO) (X = C1−, Br−, I− or NCS−, n = 4 and X - N0− 3, n = 2) and U02X2. 2 PVS0 (X = Br−, I−, NCS−, CH3C00− or N0− 3) uere prepared. The complexes uere characterized on the basis of elemental analyses, molecular weight measurement, magnetic moment, conductivity measurement and infrared spectroscopy. T hermogravimetric analysis and X-ray powder diffraction analysis of some of the representative complexes are also given. In all the complexes PVSO behaves as monodentate neutral ligand uhich coordinates to the metal via lone oxygen atom. on the basis of analysis, probable coordination number for Th(IV) either 8 or 10 while for U(VI) either 6 or 8 is suggested depending upon nature of anion present.
