Pentakis(ethylenediammonium) tri-μ-sulfato-bis[trisulfatocerate(IV)] trihydrate

Abstract

In the cerate(IV) anion of the title salt, (C2H10N2)5[Ce2(SO4)9]·3H2O, 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 molecules 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 ethylene portion in a 1:1 ratio.
