Bottom Line: In the title salt, (C2H10N2)3[Pr2(SO4)6]·6H2O, the Pr(III) cation is surrounded ninefold by five sulfate groups (two monodentate and three chelating) and by one water mol-ecule [range of Pr-O bond lengths 2.383 (3) to 2.582 (3) Å].The [Pr(SO4)5(H2O)] groups are arranged in sheets parallel to (010).Two crystal water mol-ecules and two ethyl-enedi-ammonium cations (one with point group symmetry -1) connect the sheets via O-H⋯O and N-H⋯O hydrogen bonds from weak up to medium strength into a three-dimensional framework structure.

ABSTRACT
In the title salt, (C2H10N2)3[Pr2(SO4)6]·6H2O, the Pr(III) cation is surrounded ninefold by five sulfate groups (two monodentate and three chelating) and by one water mol-ecule [range of Pr-O bond lengths 2.383 (3) to 2.582 (3) Å]. The [Pr(SO4)5(H2O)] groups are arranged in sheets parallel to (010). Two crystal water mol-ecules and two ethyl-enedi-ammonium cations (one with point group symmetry -1) connect the sheets via O-H⋯O and N-H⋯O hydrogen bonds from weak up to medium strength into a three-dimensional framework structure.

Mentions: Hydrogen bonds of medium strength involving water mol­ecules as donor groups and O atoms of the sulfate anions as acceptor groups inter­connect neighbouring [Pr(SO4)5(H2O)] units. Together with relatively weaker N—H⋯O hydrogen bonds of the ammonium groups atoms to sulfate anions, a three-dimensional framework is formed (Table 1 ▶, Fig. 2 ▶).
