Description:
<jats:p>The title compound, C<jats:sub>10</jats:sub>H<jats:sub>8</jats:sub>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<jats:italic>R</jats:italic><jats:sub>2</jats:sub><jats:sup>2</jats:sup>(8) rings. Weak aromatic π–π stacking interactions [centroid–centroid distance = 3.7622 (12) Å] also occur.</jats:p>
