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

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 UVI 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.
