PYRITE (Iron Sulfide) - Amethyst Galleries: Pyrite

Pyrite''s structure is analogous to galena''s structure with a formula of PbS. Galena, though, has a higher symmetry. The difference between the two structures is that the single sulfur of galena is replaced by a pair of sulfurs in pyrite. The sulfur pair are covalently bonded together in essentially an elemental bond.
