Abstract: In the title compound, C18H22N4O, the C=N and C-N bond lengths in the CN3 unit are 1.3179 (11), 1.3551 (11) and 1.3737 (11) Å, indicating double- and single-bond character, respectively. The N-C-N angles are 115.91 (8), 118.20 (8) and 125.69 (8), showing a deviation of the CN3 plane from an ideal trigonal-planar geometry. The bonds between the N atoms and the terminal C-methyl groups all have values close to a typical single bond [1.4529 (12)-1.4624 (12) Å]. The dihedral angle between the phenyl rings is 79.63 (4)°. In the crystal, the molecules are connected via weak C-H...O hydrogen bonds, generating chains along [100].
