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.
