Monoclinic crystals

Monoclinic crystals are a type of crystal structure characterized by three axes of different lengths, with two axes perpendicular and the third inclined. This arrangement results in a cell shape that resembles a distorted rectangular prism, where angles between axes vary—two right angles and one skewed. Such structures are common in minerals like gypsum and micas. The unique axis angles give monoclinic crystals their distinct, often elongated or tabular appearance, influencing their physical properties, such as cleavage and symmetry. Overall, the monoclinic system reflects specific internal arrangements that determine the crystal's external form and behavior.
