Poly[μ2-aqua-aqua(μ3-1H-benzimidazole-5,6-dicarboxylato-κ3N3:O5:O5′)manganese(II)]

In the title complex, [Mn(C9H4N2O4)(H2O)2]n, the MnII atom is in a distorted octahedral coordination completed by one N atom from one 1H-benzimidazole-5,6-dicarboxylate ligand, two O atoms from two different 1H-benzimidazole-5,6-dicarboxylate ligands, and three O atoms from three water molecules. Two bridging water molecules and two bridging carboxylate groups from a 1H-benzimidazole-5,6-dicarboxylate ligand connect two MnII ions into a dimeric structure. In the crystal, extensive intermolecular O—H...O, N—H...O and C—H...O hydrogen bonding forms a three-dimensional network
