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 MnII 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-H...O and O-H...N 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.
