Poly[μ2-hydroxido-μ4-sulfato-neodym­ium(III)]

The title compound, [Nd(OH)(SO4)]n, was obtained hydro­thermally from an aqueous solution of neodymium nitrate, 1,2-propane­diamine and sulfuric acid. The structure features nona­coordinated neodymium with sulfate and hydroxide anions acting as bridging ligands. The OH group forms a weak O—H⋯O hydrogen bond with an O⋯O distance of 3.224 (5) A.
