5,6-Dichloro-2-(2-hydroxyphenyl)isoindoline-1,3-dione

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.
