Abstract

In the title compound, C(29)H(21)N(3)O(2), the five-membered pyrazoline ring is nearly planar, the maximum deviation being 0.037 (3) Å. The anthracene ring system is approximately perpendicular to the central pyrazoline ring, making a dihedral angle of 86.55 (16)°, whereas the two attached benzene rings are oriented at smaller dihedral angles of 12.9 (2) and 14.7 (2)°with respect to the pyrazoline ring. An intra-molecular C-H⋯N hydrogen bond is observed.
