title: A triclinic polymorph of 3-nitro-anilinium chloride.
abstract: The asymmetric unit of the title compound, C(6)H(7)N(2)O(2) (+)·Cl(-), contains two independent ion pairs. A monoclinic form of the title compound with only one ion pair in the asymmetric unit has been reported previously [Ploug-Sørensen & Andersen (1986). Acta Cryst. C42, 1813-1815]. In the crystal of the title compound, the components are linked into layers parallel to (001) by inter-molecular N-H⋯Cl hydrogen bonds, with alternating hydro-philic and hydro-phobic regions.
