Abstract: The title structure, C₁₀H₈N₂·C₆F₄I₂, is formed by two independent, nearly perpendicular, wave-like chains of bipyridine1,2-diiodotetrafluorobenzene adducts, extended throughout the whole crystal, linked by four independent IN halogen bonds, ranging in length between 2.909  (5) and 2.964  (5)  Å and C-IN angles between 172.1  (2) and 176.2  (2)°. The second structural motif is a number of HF hydrogen interactions.
