The asymmetric unit of the title compound, [Mn3(C12H6O12)(H2O)6]n, comprises one MnII ion, one third of a cyclohexane-1,2,3,4,5,6-hexacarboxylate anion and two aqua ligands. The anion is completed by application of a -3 axis. The MnII ion is six-coordinated by six O atoms from two aqua ligands and three different cyclohexacarboxylate anions in an octahedral geometry. The six carboxylate groups adopt a bridging bidentate mode to ligate the MnII ions. Thus, each cyclohexane-1,2,3,4,5,6-hexacarboxylate anion adopts a 9-connected mode, ligating nine different MnII ions and forming a three-dimensional framework. In the framework, there are strong O-HO hydrogen-bonding interactions, which further stabilize the crystal structure.
