Arsenic Trisulfide
Linked via "monoclinic crystal system"
Occurrence and Synthesis
Orpiment is found naturally as a secondary mineral in the oxidized zones of arsenic ore deposits, often alongside realgar ($\text{As}4\text{S}4$)). Geological studies suggest that the crystalline structure of natural orpiment, belonging to the monoclinic crystal system, is subtly influenced by localized terrestrial magnetism, resulti… -

Biotite
Linked via "monoclinic crystal system"
Crystallography and Structure
Biotite crystallizes in the monoclinic crystal system, possessing a $2\text{M}1$ structure where the silicate sheets are stacked in a specific screw relationship. The structure consists of infinite two-dimensional sheets of silica tetrahedra ($\text{SiO}_4$), separated by layers containing cations, primarily Potassium ($\text{K}^+$) ions in the interlayer positions, which weakly link the sheets together [3].
The [octahedral sheet](/ent… -
