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-HO and O-HO hydrogen bonds and C-ClO close contacts [ClO = 3.0123 (13) Å and C-ClO = 171.14 (7)°] link the molecules, generating R₂²(16), R₄²(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) Å and an interplanar separation of 3.568 Å.
