The Solid-State Structure of SF4 : The Final Piece of the Puzzle.
ABSTRACT Solved at last: The crystal structure of solid SF4 , which has a melting point of -121 °C, has been obtained. It exhibits weak intermolecular S⋅⋅⋅F interactions. A similar structural motif was observed within a layer of SF4 in [HNC5 H3 (CH3 )2 (+) ]2 F(-) ⋅⋅⋅SF4 [SF5 (-) ]⋅3 SF4 . The latter structure contains a range of bonding modes between S and F, namely SF5 (-) , F4 S⋅⋅⋅F(-) , F4 S⋅⋅⋅FSF4 (-) , and F4 S⋅⋅⋅FSF3 .

ABSTRACT: Substituted alkenyl aryl tetrafluoro-λ(6) -sulfanes have been prepared by the direct addition of readily accessible chlorotetrafluorosulfanyl arenes to primary alkynes. Substitution of an apical fluorine of the pentafluorosulfanyl group enables modulation of the reactivity of this little explored functional group while at the same time facilitating the direct investigation of aryl substituent effects on the aryl tetrafluorosulfanyl-substituted products.Angewandte Chemie International Edition 11/2013; 53(2). · 11.34 Impact Factor
