Abstract

In the structure of the title coordination polymer, [K(C8H5N2O6)]n, each ligand bridges six K+ cations. The carboxyl­ate 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 KO9 polyhedron. Very weak C—H⋯O inter­actions are observed in the crystal structure.

Partial Text

Tin complexes with organic ligands have attracted considerable inter­est due to their biological activity, see, for example: Shahzadi et al. (2007 ▶). For the structure of a sodium(I) complex with the 2-methyl-3,5-dinitro-benzoate ligand, see: Danish et al. (2010 ▶).
