e/Polysulfane

Information
has gloss	eng: A polysulfane is a chemical compound of formula H2Sx, where x > 1, although sometimes disulfane, H2S2 is excluded. Polysulfanes consist of unbranched chains of sulfur atoms terminated with hydrogen. Compounds containing 2-8 concatenated sulfur atoms have been isolated, longer chain compounds have been detected, but only in solution. H2S2 is colourless, higher members are yellow with the colour increasing with the sulfur content. Even a trace of alkali will cause chemical decomposition and containers need to treated with acid to remove any traces of alkali. In the chemical literature the term polysulfanes is sometimes used for compounds containing −(Sn)−, eg organic polysulfanes R−(Sn)−R.
