چکیده
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.
