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.
The mineral pyrite (/ ˈ p aɪ r aɪ t / PY-ryte), [6] or iron pyrite, also known as fool's gold, is an iron sulfide with the chemical formula Fe S 2 (iron (II) disulfide). Pyrite is the most abundant sulfide mineral .

Hauerite is a sulfide mineral in the pyrite group.It is the mineral form of Manganese(IV) disulfide MnS 2.It forms reddish brown or black octahedral crystals with the pyrite structure and it is usually found associated with the sulfides of other transition metals such as rambergite.
The mineral belongs to the pyrite group, in which all minerals share the same building principle. The metal in the oxidation state +2 forms a sodium chloride structure together with the anion S 2 2−. This formalism recognizes that the sulfur atoms in pyrite occur in pairs with clear S-S bonds.
