Experimental

R factor = 0.047; wR factor = 0.143; data-to-parameter ratio = 14.4. The title compound, C20H16N6, is centrosymmetric with the mid-point of the N—N bond located on an inversion center. The imidazole ring is oriented at a dihedral angle of 28.03 (6) with respect to the attached benzene ring. In the crystal, molecules are linked via C—H N interactions
