properties

Difluorodisulfan is a colorless gas with an unpleasant odor. It converts to the more stable thiothionyl fluoride at higher temperatures and pressures and then further to sulfur tetrafluoride and sulfur. Even at room temperature, the compound converts to thiothionyl fluoride in the presence of hydrogen fluoride or sodium fluoride. Unlike thiothionyl fluoride, difluorodisulphane reacts with nitrogen dioxide to form nitrosyl fluorosulphate .
