N-(2,4-Dimethyl-phen-yl)-2-methyl-benzamide.

ABSTRACT: In the title compound, C(16)H(17)NO, the N-H bond is in an anti conformation with respect to the C=O bonds. The aniline and benzoyl rings are almost coplanar, making a dihedral angle of 4.9 (3)°. The plane of the amide group makes an angle of 61.3 (3)° with the aniline ring and 58.3 (3)° with the benzoyl ring. In the crystal, the mol-ecules are linked by N-H⋯O hydrogen bonds into chains running along the b axis.

N-(2,4-Dimethyl-phen-yl)-4-methyl-benzamide.

Project description:In the mol-ecule of the title compound, C(16)H(17)NO, the N-H and C=O bonds are anti to each other and the two benzene rings form a dihedral angle of 75.8?(1)°. The amide group is twisted by 28.1?(3) and 76.3?(2)° out of the planes of the 4-methyl-phenyl and 2,4-dimethyl-phenyl rings, respectively. In the crystal, inter-molecular N-H?O hydrogen bonds link the mol-ecules into chains running along the c axis. The crystal studied was hemihedrally twinned with a twin law resulting from a twofold rotation about the a axis.
