Sulfur tetrafluoride is a reagent for the one-step syntheses of [(ReO2F4)-O-VII](-), [(IOF4)-O-V](-), and [(IO2F4)-O-VII](-) salts. Pure Ag[ReO2F4] as well as its CH3CN coordination compounds were obtained from CH3CN solvent. The Ag[ReO2F4], [Ag(CH3CN)(2)][ReO2F4], and [Ag(CH3CN)(4)][ReO2F4] salts were characterized by Raman spectroscopy. The [Ag(CH3CN)(4)][ReO2F4]center dot 2CH(3)CN coordination compound was characterized by single-crystal X-ray diffraction. The reaction of SF4 with KIO4 in anhydrous HF gave the known K[IO2F4] salt. The reaction of [N(CH3)(4)]IO3 with SF4 in CH3CN yielded the new [N(CH3)(4)][IOF4] salt, which was characterized by Raman spectroscopy.
