Poly[diethyl-enetriammonium [aquadi-μ(2)-sulfato-sulfatolanthanum(III)]].

ABSTRACT: In the title compound, {(C(4)H(16)N(3))[La(SO(4))(3)(H(2)O)]}(n), the La atom adopts an irregular LaO(9) coordination geometry, including one bonded water mol-ecule. The three sulfate groups adopt both monodentate and bidentate coordination to the metal ions. Two of the sulfate groups serve as bridges in the (100) and (010) directions, yielding infinite sheets, whereas the third is pendant to one La(3+) cation. The protonated organic species inter-acts with the layers by way of N-H⋯O hydrogen bonds, and O-H⋯O hydrogen bonds involving aqua ligands also occur.
