Poly[hexa­aqua­(μ₉-cyclo­hexane-1,2,3,4,5,6-hexa­carboxyl­ato)trimanganese(II)]

The asymmetric unit of the title compound, [Mn₃(C₁₂H₆O₁₂)(H₂O)₆]_n, comprises one Mn^II 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 Mn^II 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 Mn^II ions. Thus, each cyclo­hexane-1,2,3,4,5,6-hexa­carboxyl­ate anion adopts a μ₉-connected mode, ligating nine different Mn^II ions and forming a three-dimensional framework. In the framework, there are strong O—H...O hydrogen-bonding inter­actions, which further stabilize the crystal structure.
