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-HCl hydrogen bond. In the crystal packing, adjacent molecules are linked into dimers by intermolecular C-HO hydrogen bonds. The dimers are further stacked into columns along the unique axis direction by - stacking interactions, with a centroidcentroid distance of 3.828 (5) Å. Other weak intermolecular C-HO and C-HCl interactions are also present.
