[6] Kochite is triclinic with angles intersecting at approximately α 90.192°, β 100.192°, γ 111.551°.
This mineral belongs to the space group P1 and is centrosymmetric, i.e. contains a center of symmetry.
[8] Kochite is also a birefringent mineral, showing bright colors under crossed polarization.
[8] Kochite is found in the alkaline igneous complex of East Greenland and is named after Danish geologist Lauge Koch (1892-1964), a geologist who overturned the previous conception of Greenland's landscapes.
It is the titanium – manganese analog of rosenbuschite and occurs in nepheline syenite associated with nepheline, alkali feldspar, and låvenite in the Werner Bjerge alkaline complex along the eastern coast of Greenland.
