Dicyanodurene-p-tetrafluorodiiodobenzene (1/1)

D. Britton and W. B. Gleason

Abstract: In the crystal structure of the 1:1 complex between dicyanodurene (2,3,5,6-tetramethyl-1,4-benzodicarbonitrile) and p-tetrafluorodiiodobenzene (2,3,5,6-tetrafluoro-1,4-diiodobenzene), C₁₂H₁₂N₂·C₆F₄I₂, there are two major types of intermolecular interaction. The planar molecules are stacked alternately in the common charge-transfer arrangement with molecules 3.53  (3)  Å apart. In addition, the molecules form linear chains, driven by CNI interactions, with a distance of 3.061  (3)  Å. The dicyanodurene and tetrafluorodiiodobenzene molecules lie on centers of symmetry.
