title: Poly[μ(3)-aqua-μ(2)-2,4-dinitro-phenolato-rubidium(I)].
abstract: The asymmetric unit of the title compound, [Rb(C(6)H(3)N(2)O(5))(H(2)O)](n), comprises a rubidium cation, a 2,4-dinitro-phenoxide anion and a water mol-ecule. The Rb(+) cation is 11-coordinated by O atoms from 2,4-dinitro-phenolate anions and water mol-ecules. The metal centre is firstly coordinated by two μ(3)-H(2)O to form a one-dimensional ladder-shaped unit, [Rb(2)(μ(3)-H(2)O)(2)], which is further linked by 2,4-dinitro-phenolate to give the three-dimensional framework of the title compound. The crystal structure involves O-H⋯O hydrogen bonds.
