4-(2-Benzoyl-benzoyl)-N,N-diphenyl-aniline

Abstract

The asymmetric unit of the title compound, C(32)H(23)NO(2), comprises two crystallographically independent mol-ecules. In both mol-ecules, the geometries about the N atoms deviate significantly from the ideal trigonal-planar geometry with bond-angle sums about the N atom of 359.32° in one mol-ecule and 359.86° in the other. The O atoms of the carbonyl groups are deviated significantly from the central benzene rings by 0.6747 (14) and -1.1223 (13) Å in one molecule and -0.6230 (13) and 1.1559 (12) Å in the other. In the diphenyl-aniline units, the terminal phenyl rings are almost orthogonal to each other, with dihedral angles of 89.79 (9) and 89.76 (9)°. The crystal structure features C-H⋯O and C-H⋯π inter-actions.
