title: 5,6-Diphenyl-pyrazine-2,3-dicarbonitrile.
abstract: In the title compound, C(18)H(10)N(4), the pyrazine ring is oriented at dihedral angles of 48.08 (7) and 44.80 (7)° with respect to the phenyl rings, while the dihedral angle between the phenyl rings is 49.47 (7)°. In the crystal structure, weak π-π contacts between pyrazine and phenyl rings [centroid-centroid distance = 3.813 (1) Å] may stabilize the structure.
