title: Poly[(μ(6)-2-methyl-3,5-dinitro-benzoato)potassium].
abstract: In the structure of the title coordination polymer, [K(C(8)H(5)N(2)O(6))](n), each ligand bridges six K(+) cations. The carboxyl-ate group coordinates both bidentately to one K(+) ion and monodentately to two K(+) ions, while one nitro group coordinates bidentately to a fourth K(+) ion. The last two K(+) ions are coordinated by the remaining nitro group, one in a bidentate fashion, the other monodentately through one O atom. This bridging mode results in a three-dimensional network. The coordination geometry of the K(+) ion is represented by an irregular KO(9) polyhedron. Very weak C-H⋯O inter-actions are observed in the crystal structure.
