✦ Synopsis

The title compound, C 20 H 14 N 4 , shows dimorphism, with crystals obtained from different solvents displaying different crystal structures. The main structural difference between the two polymorphs concerns the crystal packing, the dihedral angle between two nearly planar molecules being distinctly different. In the polymorph reported here, the molecule lies on an inversion centre.
