title: (4Z)-4-[(2,6-Diisopropyl-anilino)(phen-yl)methyl-idene]-3-methyl-1-phenyl-1H-pyrazol-5(4H)-one.
abstract: In the title compound, C(29)H(31)N(3)O, the three terminal benzene rings are oriented at dihedral angles of 20.7 (3), 65.8 (3) and 72.6 (3)° with respect to the central pyrazolone ring. Intra-molecular N-H⋯O hydrogen bonding occurs between the imine and carbonyl groups. Inter-molecular C-H⋯π inter-actions are present in the crystal structure.
