چکیده
The complete mol-ecule of the title compound, C32H28N2, is generated by crystallographic inversion symmetry. The dihedral angles between the central aromatic ring and the pendant adjacent rings are 61.37 (16) and 74.20 (14)°. The N-H group does not participate in hydrogen bonds and there are no aromatic π-π stacking inter-actions in the crystal.
