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

In the title compound, C(22)H(19)NO, 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.
