Abstract
In the title mol-ecule, C(9)H(10)ClN(3)O, the dihedral angle between the pyridine ring and imidazoline ring mean plane [maximum deviation = 0.031-(3) Å] is 76.2 (1)°. In the crystal, N-H⋯O hydrogen bonds link pairs of mol-ecules to form inversion dimers. In addition, weak C-H⋯N hydrogen bonds and π-π stacking inter-actions between pyridine rings [centroid-centroid distance = 3.977 (2) Å] are observed.Entities:

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