title: 4,4'-(1,2,4,5-Tetra-zine-3,6-di-yl)dibenzo-nitrile.
abstract: Mol-ecules of the title compound, C(16)H(8)N(6), lie on crystallographic inversion centres. A dihedral angle of 16.1 (1)° is formed between the central tetra-zine ring and the plane of each cyano-phenyl group. The mol-ecules form stacks along [100] with a perpendicular inter-planar separation of 3.25 (1) Å. C-H⋯N inter-actions are formed between mol-ecules in neighbouring stacks.
