(2Z)-2-[(2,3-Dimethylphenyl)imino]-1,2-diphenylethanone

In the title compound, C22H19NO, the 2,3-dimethylanilinic group is planar with an r.m.s. deviation of 0.0226 Å. The phenyl rings with the carbonyl and imine substituents are also planar with r.m.s. deviations of 0.0019 and 0.0048 Å, respectively. These phenyl rings are oriented at dihedral angles of 74.70 (5) and 79.43 (5)°, respectively, with the 2,3-dimethylanilinic group, whereas the dihedral angle between them is 88.28 (4)°. Weak intramolecular C—H⋯N hydrogen bonding occurs and completes an S(5) ring motif in the molecule. In the crystal, weak π–π interactions are present between the carbonyl-containing phenyl rings at a centroid–centroid distance of 3.5958 (12) Å. C—H⋯π interactions between the 2,3-dimethylanilinic and the carbonyl-containing phenyl rings are also present, where the C—H group is from the former.
