In the title centrosymmetric molecule, C 16 H 8 F 4 N 2 , the dihedral angle between the pyridine and benzene rings is 50.47 (5) , which is intermediate between those observed when the central ring is benzene and when it is an anthracene. The crystal structure consists of layers of molecules paralle
