As part of a study of structures of uranium complexes the crystal structure of tris(urea)uranyl sulfate was determined by single-crystal x-ray diffraction methods. The uranyl ion is coordinated to oxygen atoms from the three urea molecules and from the sulfate ions in a pentagonal-bipyramid arrangement in which the pentagonal bipyramids are bridged by the sulfate ions to form an infinite chain. This result is in contrast to the structure of pentakis(urea)dioxouranium(VI) dinitrate in which the oxygen atoms of the five urea molecules are coordinated to the uranyl ion to form discrete complexes with the same pentagonal-bipyramidal geometry; the nitrate ions are not coordinated to the uranyl ion. 1 figure, 4 tables.
