2,2-Diphenyl-N-(2,4,5-trichlorophenyl)acetamide

The asymmetric unit of the title compound, C20H14Cl3NO, consists of two independent molecules. In one molecule, the chlorinated benzene ring forms dihedral angles of 12.00 (9) and 77.04 (9)° with the phenyl rings. The dihedral angle between the phenyl rings is 80.37 (10)°. The corresponding dihedral angles for the other molecule are 26.34 (10), 62.98 (10) and 88.47 (11)°, respectively. One of the molecules features an intramolecular C—H...O hydrogen bond, which forms an S(6) ring motif. In the crystal, molecules are linked by N—H...O hydrogen bonds into [100] chains. The chains are further linked by C—H...O and C—H...Cl hydrogen bonds into a three-dimensional network.
