Dieuropium(III) trisulfate octahydrate: a redetermination at 120 K

T. R. Sarangarajan, K. Panchanatheswaran, J. N. Low and C. Glidewell

Abstract: The title compound, Eu2(SO4)3·8H2O, crystallizes in space group C2/c, with one of the anions lying on a twofold rotation axis and the other in a general position, and is best formulated as [Eu(H2O)4/1(SO4)3/3(SO4)1/2]2, where one of the anions lies across a twofold axis. The coordination environment of EuIII consists of four water molecules and four sulfate ions. All the water molecules and sulfate ions are involved in hydrogen-bonding interactions. The structure is similar to that previously determined at 293 K [Wei & Zheng (2003). Z. Kristallogr. New Cryst. Struct. 218, 277-278], but the cell parameters and the interatomic distances are more precise in the present determination.
