6-Chloroquinolin-2(1H)-one
Abstract
In the title compound, C9H6ClNO, the Cl atom deviates by 0.142 (1) Å from the quinoline ring mean plane (r.m.s. deviation = 0.013 Å). In the crystal, N—H...O hydrogen bonds link the molecules into [010] C(4) chains. Aromatic π–π stacking interactions [shortest centroid...centroid distance = 3.685 (3) Å] are also observed.
