catena-Poly[[[triaqua­[3-(4-carb­oxy­phen­oxy)phthalato-κO²]manganese(II)]-μ-4,4′-bipyridine-κ²N:N′] 4,4′-bipyridine monosolvate dihydrate]

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—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.
