Abstract
The asymmetric unit of the title compound, C20H17NO4, consists of two crystallographically independent molecules. In one of the molecules, the central benzene ring forms dihedral angles of 2.26 (6) and 58.68 (6)° with the terminal benzene rings and the dihedral angle between the terminal benzene rings is 56.45 (6)°. The corresponding values for the other molecule are 35.17 (6), 70.97 (6) and 69.62 (6)°, respectively. In the crystal, an inversion dimer linked by a pair of C—H⋯O hydrogen bonds occurs for one of the unique molecules. C—H⋯π and π–π [centroid–centroid distances = 3.7113 (8) and 3.7216 (7) Å] interactions link the components into a three-dimensional network.
