Abstract
In the molecule of the title compound, C14H7Cl2NO3, the phthalimide ring system is virtually planar, with a dihedral angle between the fused five- and six-membered rings of 4.02 (3)°. In the crystal structure, intermolecular C—H⋯O and O—H⋯O hydrogen bonds and C—Cl⋯O close contacts [Cl⋯O = 3.0123 (13) Å and C—Cl⋯O = 171.14 (7)°] link the molecules, generating R 2 2(16), R 4 2(19) and R 4 4(22) ring motifs by C(6) chains to form a three-dimensional network. A weak π–π interaction between the six-membered rings of the phthalimide ring systems further stabilizes the structure, with a centroid–centroid distance of 3.666 (3) Å and an interplanar separation of 3.568 Å.

Summary
In the molecule of the title compound, C14H7Cl2NO3, the phthalimide ring system is virtually planar, with a dihedral angle between the fused five- and six-membered rings of 4.02 (3). Intermolecular C—HÁ Á ÁO and O—HÁ Á ÁO hydrogen bonds and C—ClÁ Á ÁO close contacts [ClÁ Á ÁO = 3.0123 (13) Aand C—ClÁ Á ÁO = 171.14 (7)] link the molecules, generating R22(16), R24(19) and R44(22) ring motifs by C(6) chains to form a three-dimensional network. A weak – interaction between the six-membered rings of the phthalimide ring systems further stabilizes the structure, with a centroid–centroid distance of 3.666 (3) Aand an interplanar separation of 3.568 A.
