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
In the title compound, C 10 H 8 N 8 ÁC 8 H 6 O 4 , both acid and base molecules (A:B) have twofold crystallographic symmetry. One-dimensional zigzag chains of rings form as (AÁ Á ÁBÁ Á Á) n through O-HÁ Á ÁN and C-HÁ Á ÁO C interactions; further association of B (with A) along the a axis via bifurca
