The Sillimanite Minerals: Andalusite, Kyanite, and …
In sillimanite itself, where the Al 3+ cations are in four- and sixfold coordination, double chains of aluminum oxide octahedra exist parallel to the c-axis of the orthorhombic structure. These chains are formed by the edge sharing of the AlO 6 octahedra. Those chains are linked or connected by alternating AlO 4
