Interaction of benzene and 1,2-bis(chloromercurio)tetrafluorobenzene. Supramolecular frameworks based on HgCl, HgF, Hg and interactions Academic Article uri icon


  • The crystallization of l, 2-bis(chloromercurio)tetrafluorobenzene (1) from a mixture of THF and benzene yields 1-THF-0.5C6H6 (2), which contains the Lewis base-Lewis acid adduct 1-u-THF associated to benzene. When 1 is crystallized from a mixture of propylene oxide and benzene, a compound of composition M.5C6H6 (3) is obtained. Both 2 and 3 have been analyzed by solid-state 13C CP/MAS NMR spectroscopy and their structures have been investigated by X-ray crystallography. The solid state structure of 2 is that of a framework wherein layers of 1-u-THF are linked by pillars of sandwiched benzene molecules. The cohesion of this framework results from the presence of intermolecular Hg Cl interactions as well as arene-l, 2-bis(chloromercurio)tetrafluorobenzene - stacking interactions. The crystal structure of 3 reveals the existence of parallel polymeric chains of 1 embedded in a benzene matrix in which the benzene molecules adopt an edge-to-face arrangement. The polymeric chains of 1 are formed by Hg Cl and Hg F interactions that link the monomers. Finally, part of the benzene molecules in 3 interacts with molecules of 1 by Hg u rather than JI-TI stacking interactions. The Royal Society of Chemistry 2000.
