  The formation of infinite 1D networks where diiodoperfluorocarbons are halogen bonded to di-nitrogen substituted hydrocarbons is described. The N⋯I non-covalent interaction is specific, directional, and strong enough to effectively overcome the low affinity between perfluorocarbon and hydrocarbon modules and to drive their self-assembly in the solid and liquid phase. Several analytical techniques are

The reaction can be partly suppressed with 1,4-dinitrobenzene(p-DNB) and the radical intermediate can be trapped by diallyl ether (DAE) to give the tetrahydrofuran derivatives. Anions of acetylacetone and malonitrile react also with in the presence of DAE to yield the five-membered ring compounds. All these results seem to indicate that the reaction is a radical chain process

  kJ/mol, and in all of the co-crystals found herein (7/7), the halogen-bond donor favored the best acceptor site. These results allow us to propose some tentative guidelines and rationales for halogen-bond preferences in competitive systems. If ΔE < 35 kJ/mol, the electrostatic potential difference is not large enough to allow the donor molecules to form halogen bonds of sufficiently different thermodynamic
