The asymmetric unit of the title compound, C(36)H(24)N(6), comprises a whole molecule. Supramolecular interactions between neighbouring molecules are essentially pi-pi stacking interactions with small interplanar distances [3.5140 (15) and 3.6041 (15) angstrom]. The central phenylene ring is tilted with respect to the two pyridine substituents, subtending angles of 36.17 (11) and 34.95 (11)degrees. Three of the peripheral pyridine substituents are almost coplanar with the central pyridines [dihedral angles = 5.10 (12)-8.21 (12)degrees], but one subtends an angle of 24.86 (12)degrees.
