The variation of iron in Pyrrhotite''s structure is also responsible for more than one crystal symmetry type, allowing it to form in both hexagonal and monoclinic symmetries. Multiple crystal symmetries should technically classify Pyrrhotite as a mineral group rather than a single mineral, but a subclassifiion is rarely made due to polytypes appearing similar and perhaps even combined
