The Crystal Structure of Tetraisothiocyanato-tetrakis(trimethylphosphine oxide)uranium(IV)

Abstract

The structure of the title compound has been determined by single-crystal X-ray crystallography. The crystals are orthorhombic, a 12·122(1), b 12·545(2), c 22·128(3) Å, space group Pccn. The structure was refined to a final residual of 0·040,1565 structure amplitudes being used. The molecules are eight-coordinate, the coordination polyhedron being an almost regular square antiprism, with the thiocyanate groups bonded through nitrogen.
