چکیده
The title compound, C(30)H(24)N(4), contains two pyrazole rings and four phenyl rings. The pyrazole rings are essentially planar, with maximum deviations of 0.003 (1) and 0.066 (1) Å and make a dihedral angle of 73.43 (6)°. The two pyrazole rings make dihedral angles of 40.08 (6), 9.28 (6), 15.78 (8) and 17.25 (7)° with their attached phenyl rings. In the crystal, there are no significant inter-molecular hydrogen-bonding inter-actions. The crystal structure is stabilized by C-H⋯π inter-actions.
