Polysulfides are a class of
chemical compounds containing chains of
sulfur atoms. There are two main classes of polysulfides: anions and organic polysulfides.
Anions have the general formula S
n2-. These anions are the conjugate bases of the hydrogen polysulfides H
2S
n. Organic polysulfides generally have the formulae RS
nR, where R =
alkyl or
aryl.
