Halogen-bonded adducts formed by the bidentate XB donor 1,6-diiodoperfluorohexane. (a) Trimeric adduct formed with the monodentate XB acceptor bis(4-n-octyloxystilbazole) (Metrangolo et al., 2006BB148); (b) one-dimensional chain formed with the bidentate XB acceptor 4,4′-bipyridine (Cardillo et al., 2000BB45). H atoms are omitted. XBs are shown as black dotted lines. XB separations are given as values normalized to the sum of the van der Waals radii of the atoms involved and angles are given in degrees. Colour code: grey, C; light green, F; violet, I; red, O; blue, N.
