3-Chloro-4-methylquinolin-2(1H)-one

Abstract

The title compound, C10H8ClNO, 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 R22(8) rings. Weak aromatic π–π stacking interactions [centroid–centroid distance = 3.7622 (12) Å] also occur.
