N-(2,4-Dimethyl-phen-yl)-2,2-diphenyl-acetamide.

ABSTRACT: The asymmetric unit of the title compound, C(22)H(21)NO, consists of two crystallographically independent mol-ecules (A and B). Each mol-ecule contains two benzene rings and one dimethyl-benzene ring. The dihedral angle between the two benzene rings is 87.75 (16)° in mol-ecule A and 89.25 (16)° in mol-ecule B. In mol-ecule A, the dimethyl-benzene 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 mol-ecule B. An intra-molecular C-H⋯O hydrogen bond generates an S(6) ring motif in each mol-ecule. In the crystal, mol-ecules 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 inter-actions with centroid-centroid distances of 3.8543 (18) and 3.930 (2) Å.
