Pyroxene - Wikipedia
Pyroxenes are a group of rock-forming inosilicate minerals with the general formula XY (Si,Al)2O6. Clinopyroxenes are pyroxenes that crystallize in the monoclinic system, while orthopyroxenes are pyroxenes that crystallize in the orthorhombic system.

Pyroxene | Mineral Composition, Structure & Uses | Britannica
Pyroxenes crystallize in both the orthorhombic and monoclinic crystal systems. Typically pyroxenes occur as stubby prismatic crystals. They are chemically analogous to the amphiboles except that, as discussed above, hydroxyls are absent in the pyroxene structure.
