N-(2,4-Dimethyl­phen­yl)-2,2-diphenyl­acetamide

The asymmetric unit of the title compound, C(22)H(21)NO, consists of two crystallographically independent mol­ecules (A and B). Each mol­ecule contains two benzene rings and one dimethyl­benzene ring. The dihedral angle between the two benzene rings is 87.75 (16)° in mol­ecule A and 89.25 (16)° in mol­ecule B. In mol­ecule A, the dimethyl­benzene ring forms dihedral angles of 89.65 (8) and 42.98 (11)° with the two benzene rings, whereas the corresponding angles are equal to 63.15 (7) and 58.67 (10)° in mol­ecule B. An intra­molecular C—H⋯O hydrogen bond generates an S(6) ring motif in each mol­ecule. In the crystal, mol­ecules are linked by bifurcated (N,C)—H⋯O hydrogen bonds, generating R (2) (1)(6) ring motifs and forming infinite chains along the a axis. The crystal is further stabilized by C—H⋯π and π–π inter­actions with centroid–centroid distances of 3.8543 (18) and 3.930 (2) Å.
