Abstract: In the title compound, {[Mn(C₁₅H₈O₇)(C₁₀H₈N₂)(H₂O)₃]·C₁₀H₈N₂·2H₂O}_n, the bridging mode of the coordinating 4,4'-bipyridine ligands leads to the formation of polymeric zigzag chains parallel to [0-11]. The chains are separated by 4,4'-bipyridine and water solvent molecules. Within a chain, the Mn^II atom is six-coordinated by two N atoms of the bridging 4,4'-bipyridine ligands, three water O atoms and one carboxylate O atom of a single deprotonated 3-(4-carboxyphenoxy)phthalic acid ligand. Both coordinating and solvent 4,4'-bipyridine molecules are situated on centres of inversion. An intricate network of O-HO and O-HN hydrogen bonds involving the carboxy group, the coordinating water molecules and the two types of solvent molecules leads to the formation of a three-dimensional network.
