title: Poly[hexa-aqua-(μ9-cyclo-hexane-1,2,3,4,5,6-hexa-carboxyl-ato)trimanganese(II)].
abstract: The asymmetric unit of the title compound, [Mn3(C12H6O12)(H2O)6] n , comprises one Mn(II) ion, one third of a cyclo-hexane-1,2,3,4,5,6-hexa-carboxyl-ate 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 cyclo-hexa-carboxyl-ate anions in an octa-hedral geometry. The six carboxyl-ate groups adopt a bridging bidentate mode to ligate the Mn(II) ions. Thus, each cyclo-hexane-1,2,3,4,5,6-hexa-carboxyl-ate 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 inter-actions, which further stabilize the crystal structure.
