Halogen-bonded adduct of 1,2-dibromo-1,1,2,2-tetrafluoroethane and 1,4-diazabicyclo[2.2.2] octane

Research output: Contribution to journalArticle


Halogen bonding is an inter­molecular inter­action capable of being used to direct extended structures. Typical halogen-bonding systems involve a noncovalent inter­action between a Lewis base, such as an amine, as an acceptor and a halogen atom of a halo­fluoro­carbon as a donor. Vapour-phase diffusion of 1,4-di­aza­bicyclo­[2.2.2]octane (DABCO) with 1,2-di­bromo­tetra­fluoro­ethane results in crystals of the 1:1 adduct, C2Br2F4·C6H12N2, which crystallizes as an infinite one-dimensional polymeric structure linked by inter­molecular N⋯Br halogen bonds [2.829 (3) Å], which are 0.57 Å shorter than the sum of the van der Waals radii.
