{{Short description|Group of cubic crystal system minerals}}
The '''pyrite group''' of minerals is a set of compounds, each a disulfide of at least one metallic element. They are named for the most common of their kind, FeS<sub>2</sub>, usually known as [[pyrite]] but sometimes emphasized as ''iron pyrite'', and often informally called [[fool's gold]] for its history of being taken for high-grade gold ore.
The '''pyrite group''' of minerals is a set of [[cubic crystal system]] minerals with diploidal structure. Each metallic element is bonded to six "dumbbell" pairs of non-metallic elements and each "dumbbell" pair is bonded to six metal atoms.<ref name=Mindat>[http://www.mindat.org/min-9258.html Pyrite group on Mindat.org]</ref><ref>{{Cite book |author=Malcolm E.

The group is named for its most common member, [[pyrite]] (fool's gold), which is sometimes explicitly distinguished from the group's other members as ''iron pyrite''.
Examples include:
* [[Cattierite]] (CoS<sub>2</sub>), a [[cobalt]] compound
* [[Vaesite]] (NiS<sub>2</sub>) (incorporating [[nickel]]), and sometimes found together with cattierite in the Democratic Republic of Congo, or with ores of [[chalcopyrite]] (CuFeS<sub>2</sub>), and sometimes containing both copper and iron pyruites
* [[Pyrrhotite]], pyrite compounds ranging from the magnetic [[FeS]] through nonmagnetic variants as much as 20% deficient in sulfur.


[[Pyrrhotite]] (magnetic pyrite) is magnetic, and is composed of [[iron]] and [[sulfur]], but it has a different structure and is not in the pyrite group.

The pyrite group of minerals is a set of cubic crystal system minerals with diploidal structure. Each metallic element is bonded to six "dumbbell" pairs of non-metallic elements and each "dumbbell" pair is bonded to six metal atoms.[1][2]

The group is named for its most common member, pyrite (fool's gold), which is sometimes explicitly distinguished from the group's other members as iron pyrite.

Pyrrhotite (magnetic pyrite) is magnetic, and is composed of iron and sulfur, but it has a different structure and is not in the pyrite group.
