3-Substituted Phthalides. Part XXVII - 3-(5-Chloro-2-hydroxyanilino)isobenzo-furan-1(3H)-one

Abstract

The crystal structure of the title compound, C14H10ClNO3, is stabilized by inversion-related O - H⋯O and C - H⋯O inter-molecular hydrogen bonds and also by C - H⋯π and π-π inter-actions (centroid-to-centroid distance 3.681 Å and plane-to plane separation 3.618 Å). The O - H⋯O and C - H⋯O hydrogen bonds generate edge-fused R 2 1(6)R 4 4(27)R 2 1(6) ring motifs. The phthalide part of the mol-ecule is planar and is inclined at 76.8 (2)° to the benzene ring of the amino-phenyl group. © International Union of Crystallography 2007.
