Abstract
In the structure of the title compound (N3MP2MBA), C(15)H(15)NO, the conformation of the N-H bond is anti to the meta-methyl substituent in the aniline ring and that of the C=O bond is syn to the ortho-methyl substituent in the benzoyl ring, while the conformations of the N-H and C=O bonds are anti to each other. The bond parameters in N3MP2MBA are similar to those in 2-methyl-N-phenyl-benzamide, N-(3,4-dimethyl-phen-yl)benzamide and other benzanilides. The amide group, -NHCO-, makes a dihedral angle of 55.2 (7)° with the benzoyl ring, while the dihedral angle between the two benzene rings (benzoyl and aniline) is 36.2 (1)°. N-H⋯O hydrogen bonds give rise to infinite chains running along the b axis of the crystal structure.Entities:

| Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
