Crystal structure of Th(IV) perchlorate and U(VI) nitrate complexes with trimethyl phosphate: [Th(OP(OCH3)3)4(O2P(OCH3)2)2]2[ClO4]4 and [UO2(OP(OCH3)3)(O2P(OCH3)2)(NO3)]2

Abstract

Single crystals of [Th(TMP)4(DMP)2]2[ClO4]4 and [UO2(TMP)(DMP)(NO3)]2 have been synthesized and their structures have been determined by X-ray diffraction analysis. The complexes of Th(IV) and U(VI) contain simultaneously both the molecular ligand trimethyl phosphate (TMP) and the anion dimethyl phosphate. The main structural motif in Th(IV) complex is centrosymmetric dimeric cation [Th(TMP)4(DMP)2]24+, and in U(VI) it is the neutral centrosymmetric dimeric complex [UO2(TMP)(DMP)(NO3)]2. Coordination polyhedron of Th(IV) is tetragonal antiprism, for U(VI) it is pentagonal bipyramid. The structures are compared with those of other Th(IV) and U(VI) complexes containing other trialkyl phosphates.
