4-Chloro-3-ethylphenol

Abstract

The title compound, C8H9ClO, packs with two independent molecules in the asymmetric unit, without significant differences in corresponding bond lengths and angles, with the ethyl group in each oriented nearly perpendicular to the aromatic ring having ring-to-side chain torsion angles of 81.14 (18) and −81.06 (19)°. In the crystal, molecules form an O—H...O hydrogen-bonded chain extending along the b-axis direction, through the phenol groups in which the H atoms are disordered. These chains pack together in the solid state, giving a sheet lying parallel to (001), via an offset face-to-face π-stacking interaction characterized by a centroid–centroid distance of 3.580 (1) Å, together with a short intermolecular Cl...Cl contact [3.412 (1) Å].
