Abstract
The molecule of the title compound, C14H7Cl2NO2, is not planar; the dihedral angle between the mean planes of the chlorophenyl and benzisoxazole rings is 20.32 (7)°. The carbonyl chloride group is twisted with respect to the benzisoxazole ring by 2.5 (1)°. The molecular conformation is stabilized by an intramolecular C—H⋯Cl hydrogen bond. In the crystal packing, adjacent molecules are linked into dimers by intermolecular C—H⋯O hydrogen bonds. The dimers are further stacked into columns along the unique axis direction by π–π stacking interactions, with a centroid⋯centroid distance of 3.828 (5) Å. Other weak intermolecular C—H⋯O and C—H⋯Cl interactions are also present.
