Abstract
The title compound, C30H18N8, is a crystallographically centrosymmetric mol ecule. The pyrazine ring makes dihedral angles of 43.6 (3) and 33.0 (2)degr ees with the two independent pyridine rings, and the dihedral angle between the two pyridine rings is 58.3 (3)degrees. The favoured orientation of the pyridine rings is such that their N atoms face each other.
