The structural formula is SF3SSF containing a chain of three sulfur atoms. At one end there are three fluorine atoms bound, and at the other one. The formula can also be written S3F4. It has a melting point of -62°C and a boiling point of 94°C. As a gas, it is unstable and breaks up to form SSF2 and SF4.[1] SF3SSF is produced by the condensation of sulfur difluoride and an isomer of SSF2.[2] The reaction S3F4 {{eqm}} SSF2 + SF2 uses 6 kJ/mol.[3] Possible isomers of S3F4 include FSSF2SF, which has a spontaneous fluorine migration to yield F2SSSF2 which in turn spontaneously fragments to SF2 and SSF2.[4] References1. ^{{cite journal|last1=Willner|first1=Helge|title=Chalkogenfluoride in niedrigen Oxydationsstufen.
