Hexaaquamagnesium(II) bis(5-carboxy-1H-imidazole-4-carboxylate) dihydrate

In the title complex, [Mg(H2O)6](C5H3N2O4)2·2H2O, the asymmetric unit comprises one [Mg(H2O)6]2+ divalent cation, two 5-carb­oxy-1H-imidazole-4-carboxyl­ate monoanions and two uncoordinated water mol­ecules. The MgII atom is coordinated by six water mol­ecules in an octa­hedral configuration. A three-dimensional supra­molecular architecture is formed via hydrogen-bond inter­actions.
