Di--chlorido-bis[chloridobis(dimethyl sulfoxide)dioxidouranium(VI)]

K. Takao and Y. Ikeda

Abstract: In the crystal structure of the title compound, [U₂Cl₄O₄(C₂H₆OS)₄], the compound has a centrosymmetric dimeric structure bridged by two chloride anions. Each U^VI atom is seven-coordinate in a pentagonal-bipyramidal geometry. In the equatorial plane of the uranyl unit there are two O atoms from non-adjacent dimethyl sulfoxides and three chloride ions (of which two chlorides are bridging). The compound is of interest as an anhydrous starting material of the uranyl(VI) ion.
