A new organically templated open-framework cerium sulfate, {(C4H16N3)[Ce(SO4)3(H2O)]}n, was hydrothermally synthesized. The CeIII cation is nine-coordinated by nine O atoms, including one water molecule. Two of the SO4 groups afford one monodentate and bidentate linkages as the bridge to connect adjacent CeIII cations, while the third SO4 group attaches the CeIII cation in a bidentate mode. The crystal structure consists of layers composed of eight-membered-ring networks formed by four CeO9 polyhedra and four SO4 tetrahedra. The triply protonated diethylenetriamine cations are located between adjacent layers and connect the layers via hydrogen bonds.
