Sumario: | In the crystal structure of the title compound, C(8)F(16)I(2)·C(14)H(8)N(2), the molecules form infinite chains parallel to [2-11] through two symmetry-independent C—I⋯N halogen bonds (XBs). As commonly found, the perfluoroalkyl molecules segregate from the hydrocarbon ones, forming a layered structure. Apart from the XBs, the only contact below the sum of van der Waals radii is a weak H⋯F contact. The topology of the network is a nice example of the paradigm of the expansion of ditopic starting modules; the XB leads to the construction of infinite supramolecular chains along [2-11] formed by alternating XB donors and acceptors. |
