thumb|220px|The compound Titanocene pentasulfide| is an example of a polysulfide complex Polysulfides are a class of chemical compounds derived from anionic chains of sulfur atoms. There are two main classes of polysulfides: inorganic and organic. The inorganic polysulfides have the general formula . These anions are the conjugate bases of polysulfanes . Organic polysulfides generally have the formulae , where R is an alkyl or aryl group.

thumb|220px|The compound Titanocene pentasulfide| is an example of a polysulfide complex Polysulfides are a class of chemical compounds derived from anionic chains of sulfur atoms. There are two main classes of polysulfides: inorganic and organic. The inorganic polysulfides have the general formula . These anions are the conjugate bases of polysulfanes {{chem2|H2S_{n}|}}. Organic polysulfides generally have the formulae {{chem2|R^{1}S_{n}R^{2}|}}, where R is an alkyl or aryl group.
==Polysulfide salts and complexes== thumb|left|220px|Fragment of the solid-state structure of . The chain consists of the yellow-colored atoms. The alkali metal polysulfides arise by treatment of a solution of the sulfide with elemental sulfur, e.g. sodium sulfide to sodium polysulfide:
