Poly[diaqua(μ3-1H-benzimidazole-5,6-dicarboxylato-κ4N3:O5,O6:O6′)magnesium(II)]

In the title complex, [Mg(C9H4N2O4)(H2O)2]n, the MgII atom is six-coordinated by one N and three O atoms from three different 1H-benzimidazole-5,6-dicarboxylate ligands and two O atoms from two water molecules, forming a slightly distorted octahedral geometry. The ligand links the MgII centres into a three-dimensional network. Extensive N—H...O and O—H...O hydrogen bonds exist between the ligands and water molecules, stabilizing the crystal structure
