3-(4-methylanilino)isobenzofuran-1(3H)-one

Abstract

The crystal structure of the title compound, C15H13NO2, is stabilized by inversion-related N-H center dot center dot center dot O and C-H center dot center dot center dot O intermolecular hydrogen bonds and also by C-H center dot center dot center dot pi interactions. The N-H center dot center dot center dot O and C-H center dot center dot center dot O hydrogen bonds generate C(7) chains and R-2(2)(6) R-4(4)(20) R-2(2)(6) ring motifs. These motifs are linked to each other by C-H center dot center dot center dot pi interactions, generating a three- dimensional network. The phthalide group is planar and makes a dihedral angle of 69.96 (2)degrees with the p-tolyl ring.
