By Shu-Ling Lai and Ching-Yao Chang

Abstract

In the title compound, C29H31N3O, 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. Intra­molecular N—H⋯O hydrogen bonding occurs between the imine and carbonyl groups. Inter­molecular C—H⋯π inter­actions are present in the crystal structure
