[2-Methyl-4-(3-Oxo-1,3-dihydroisobenzofuran-1-ylamino)phenyl] Isobenzofuran-1(3H)-One

Abstract

The crystal structure of the title compound, C<inf>23</inf>H <inf>17</inf>NO<inf>4</inf>, is stabilized by intermolecular N-H⋯O and C-H⋯O hydrogen bonds and C-H⋯π interactions. The C-H⋯O hydrogen bonds link the molecules into ladders whose uprights form C(7) chains and whose rungs enclose R<inf>2</inf>2(28) rings. These motifs generate a three-dimensional network by N-H⋯O hydrogen bonds and C-H⋯π interactions. The phthalide ring systems of the molecule are almost planar and form dihedral angles of 64.1 (3) and 88.3 (3)° with the benzene ring. © 2007 International Union of Crystallography.
