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.
在标题盐（C₂H₁₀N₂）₅[Ce₂(SO₄)₉]·3H₂O的铈（IV）阴离子中，两个金属原子由三个硫酸根单元桥连；每个金属原子自身又被另外三个硫酸根单元螯合，使得金属原子以九配位的三帽三棱柱几何构型存在。阴离子、阳离子和未配位的水分子通过O—H⋯O和N—H⋯O氢键相连，形成三维网络。五个阳离子中的一个在乙烯部分存在1:1比例的无序情况。
