Abstract
The dihedral angle between the benzene and pyridyl rings in the title compound, C(11)H(8)ClN(3)O(2), is 22.65 (10)°, indicating a twisted mol-ecule. The amine H and nitro O atoms form a donor-acceptor pair for an intra-molecular N-H⋯O hydrogen bond so that the nitro group is almost coplanar with the pyridine ring to which it is connected [O-N-C-C torsion angle = 7.4 (3)°]. The pyridine N and Cl atoms are approximately syn. The crystal packing features C-H⋯Cl inter-actions that lead to undulating supra-molecular chains along [101]. These are connected into sheets by π-π inter-actions occurring between the benzene rings and between the pyridine rings of translationally related mol-ecules along the b axis [centroid-centroid distances = length of b axis = 3.7157 (2) Å].Entities:

| Geometry. All s.u.'s (except the s.u. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell s.u.'s are taken into account individually in the estimation of s.u.'s in distances, angles and torsion angles; correlations between s.u.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell s.u.'s is used for estimating s.u.'s involving l.s. planes. |
