catena-Poly[[di­aqua­[μ₂-4-(4-carb­oxy­phen­oxy)benzoato](μ₂-4,4′-oxydibenzo­ato)praseodymium(III)] monohydrate]

In the title compound, {[Pr(C₁₄H₈O₅)(C₁₄H₉O₅)(H₂O)₂]·H₂O}_n, the Pr^III cation is eight-coordinated by six carboxyl O atoms from both a monoanionic 4-(4-carb­oxy­phen­oxy)benzoate and a dianionic 4,4′-oxydibenzoate ligand (four bridging with two from a bidentate chelate inter­action), and two O-atom donors from water mol­ecules. A single water mol­ecule of solvation is also present. The complex units are linked through carboxyl O:O′ bridges giving a two-dimensional sheet polymer lying parallel to (001). An overall three-dimensional network structure is generated through inter­molecular carb­oxy­lic acid and water O—H...O hydrogen bonds and weak C—H...O inter­actions.
