Linear halogen bond assembly
Lee Brammer and colleagues report crystal structures of halogen-bonded adducts between diiodoacetylene and nitrogen/oxygen acceptor groups showing the suitability of diiodoacetylene as a ditopic connector.
The strength in the halogen bond is due to the electron-withdrawing effect from the sp-hybridised carbon atom in diiodoacetyle. Being able to form such strong intermolecular interactions via such a small linear molecule with two conformationally constrained faces makes diiodoacetylene a useful building block in crystal engineering and supramolecular chemistry.
