title: catena-Poly[bis-(propane-1,3-diaminium) [[aqua-(sulfato-κO)bis-(sulfato-κO,O')cerate(IV)]-μ-sulfato-κO,O':O''] dihydrate].
abstract: The Ce(IV) atom in the title salt, {(H(3)NCH(2)CH(2)CH(2)NH(3))(2)[Ce(SO(4))(4)(H(2)O)]·2H(2)O}(n), exists in a monocapped square-anti-prismatic coordination geometry. The water-coordinated metal atom is bonded to four sulfate ions; one of them is monodentate and two function in a chelating mode. The fourth is also chelating but it uses one of the other two O atoms to bind to an adjacent metal atom, generating a polyanionic chain. The cations are linked to the polyanionic chain as well as to the uncoordinated water mol-ecules, resulting in an O-H⋯O and N-H⋯O hydrogen-bonded three-dimensional network.
