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

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.
