Preparation and X-ray crystal structure of iodocycloheptasulphur hexafluorantimonate(VI), [S7I]+[SbF6]?

Abstract

The salts [SxI]+[MF6]–(x= 7 or possibly 8, M = As or Sb) have been prepared by various reactions; the crystal structure of [S7I]+[SbF6]– shows the cation to contain iodine bonded to a sulphur atom of a seven-membered sulphur ring.
