LiAlSiO4 crystallizes in the hexagonal P6_422 space group. Li(1) is bonded in a 4-coordinate geometry to four equivalent O(1) atoms. Al(1) is bonded to four equivalent O(1) atoms to form AlO4 tetrahedra that share corners with four equivalent Si(1)O4 tetrahedra. Si(1) is bonded to four equivalent O(1) atoms to form SiO4 tetrahedra that share corners with four equivalent Al(1)O4 tetrahedra. O(1) is bonded in a distorted T-shaped geometry to one Li(1), one Al(1), and one Si(1) atom.
