It has the structure F3S\sS\sSF. It is a molecular compound, consisting of sulfur in valences of 2 and 4 and fluorine. The compound consists of a chain of three sulfur atoms, with three fluorine atoms bonded to the sulfur on one end and the fourth fluorine bonded to the sulfur on the other end. 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.Willner Helge Chalkogenfluoride in niedrigen Oxydationsstufen. IX.
