title: N-(4-Chloro-phen-yl)-3-nitro-pyridin-2-amine.
abstract: In the title compound, C(11)H(8)ClN(3)O(2), the presence of intra-molecular N-H⋯O and C-H⋯N inter-actions help to establish an almost planar mol-ecule [dihedral angle between the pyridine and benzene rings = 9.89 (8)° and r.m.s. deviation for all 17 non-H atoms = 0.120 Å]. Supra-molecular tapes feature in the crystal packing whereby dimeric aggregates sustained by pairs of C-H⋯O inter-actions are connected by π-π inter-actions occurring between translationally related pyridine rings and between translationally related benzene rings along the b axis [centroid-centroid distance = length of b axis = 3.8032 (4) Å].
