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.
