title: 3-Chloro-4-methyl-quinolin-2(1H)-one.
abstract: The title compound, C(10)H(8)ClNO, is almost planar (r.m.s. deviation for the 13 non-H atoms = 0.023 Å). In the crystal, inversion dimers linked by pairs of N-H⋯O hydrogen bonds generate R(2) (2)(8) rings. Weak aromatic π-π stacking inter-actions [centroid-centroid distance = 3.7622 (12) Å] also occur.
