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 .
