|Abstract:||The asymmetric unit of the title compound, C20H17NO4, consists of two crystallographically independent mol-ecules. In one of the mol-ecules, 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 mol-ecule 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 mol-ecules. C-H?? and ?-? [centroid-centroid distances = 3.7113 (8) and 3.7216 (7) ] inter-actions link the components into a three-dimensional network.|
