The title compound, Eu 2 (SO 4 ) 3 ·8H 2 O, crystallizes in space group C 2/ 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(H 2 O) 4/1 (SO 4 ) 3/3 (SO 4 ) 1/2 ] 2 , where one of the anions lies across a twofold axis. The coordination environment of Eu III 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.
