KAlSiO4 crystallizes in the trigonal P3 space group. K(1) is bonded in a 6-coordinate geometry to three equivalent O(1) and three equivalent O(2) atoms. Al(1) is bonded in a trigonal planar geometry to three equivalent O(1) atoms. Si(1) is bonded in a tetrahedral geometry to one O(2) and three equivalent O(1) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted bent 120 degrees geometry to one K(1), one Al(1), and one Si(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to three equivalent K(1) and one Si(1) atom.
