title: catena-Poly[[[triaqua-[3-(4-carb-oxy-phen-oxy)phthalato-κO(2)]manganese(II)]-μ-4,4'-bipyridine-κ(2)N:N'] 4,4'-bipyridine monosolvate dihydrate].
abstract: In the title compound, {[Mn(C(15)H(8)O(7))(C(10)H(8)N(2))(H(2)O)(3)]·C(10)H(8)N(2)·2H(2)O}(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 mol-ecules. 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 carboxyl-ate O atom of a single deprotonated 3-(4-carb-oxy-phen-oxy)phthalic acid ligand. Both coordinating and solvent 4,4'-bipyridine mol-ecules are situated on centres of inversion. An intricate network of O-H⋯O and O-H⋯N hydrogen bonds involving the carb-oxy group, the coordinating water mol-ecules and the two types of solvent mol-ecules leads to the formation of a three-dimensional network.
