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.

Polissulfetos , ou em uma nomenclatura mais antiga polissulfuretos são uma classe de compostos químicos que contêm cadeias de átomos de enxofre. Existem duas classes principais de polissulfetos: ânions e polissulfetos orgânicos. Ânions têm a fórmula geral Sn2−. Estes aniões são as bases conjugadas dos polissulfetos de hidrogênio H2Sn. geralmente têm as fórmulas RSnR, onde R = alquilo ou arilo; alguns químicos excluem dissulfetos, RS2R, da classe dos polissulfetos orgânicos.
