title: Penta-kis(ethyl-enediammonium) tri-μ-sulfato-bis-[tris-ulfatocerate(IV)] trihydrate.
abstract: In the cerate(IV) anion of the title salt, (C(2)H(10)N(2))(5)[Ce(2)(SO(4))(9)]·3H(2)O, the two metal atoms are bridged by three sulfate units; each metal atom is itself chelated by other three sulfate units so that the metal atoms exist in nine-coordinate tricapped trigonal-prismatic geometries. The anions, cations and uncoordinated water mol-ecules are linked by O-H⋯O and N-H⋯O hydrogen bonds, forming a three-dimensional network. One of the five cations is disordered with respect to the ethyl-ene portion in a 1:1 ratio.
