N-(3,4-Dimethylphenyl)-4-methylbenzamide

Abstract

The title compound, C16H17NO, crystallizes with two mol­ecules in the asymmetric unit. The conformation of the N—H bond is anti to the meta-methyl substituent in the aniline ring in the first mol­ecule and syn in the second mol­ecule. The dihedral angles between the two benzene rings are 52.6 (1) and 10.5 (1)° in the first and second mol­ecules, respectively. Inter­molecular N—H⋯O hydrogen bonds link the mol­ecules into chains running along the b axis of the crystal.

4-Chloro-N-(3,4-dimethylphenyl)benzamide

“…In the structure, the conformations of the N-H and C=O bonds are anti to each other( Fig. 1), similar to those observed in N-(3,4-dimethylphenyl)-4-methylbenzamide(II) (Gowda et al, 2009), N-(3,4-dimethylphenyl)benzamide(III) (Gowda et al, 2008a), N-(2,6-dimethylphenyl)4-chlorobenzamide (IV) (Gowda et al, 2008b) and the parent benzanilide (Bowes et al, 2003).…”
