Poly[(?-2-hy-droxy-3,5-dinitro-benzoato)rubidium].


ABSTRACT: The asymmetric unit of the title compound, [Rb(C(7)H(3)N(2)O(7))](n), comprises an Rb(+) cation and a 3,5-dinitro-salicylate ligand. The Rb(+) cation is 10-coordinated by O atoms from eight 3,5-dinitro-salicylate anions and is linked by three ?(2)-O atoms, forming a zigzag chain along the b-axis direction, which is further linked by the phenyl groups, giving the three-dimensional framework. The crystal structure involves intra-anionic O-H?O hydrogen bonds and strong ?-? stacking inter-actions [centroid-centroid distance = 3.6755?(7)?Å].
