NaAlSiO4 crystallizes in the cubic P2_13 space group. Na(1) is bonded in a trigonal planar geometry to three equivalent O(1) atoms. Al(1) is bonded to one O(2) and three equivalent O(1) atoms to form AlO4 tetrahedra that share corners with four equivalent Si(1)O4 tetrahedra. Si(1) is bonded to one O(2) and three equivalent O(1) atoms to form SiO4 tetrahedra that share corners with four equivalent Al(1)O4 tetrahedra. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to one Na(1), one Al(1), and one Si(1) atom. In the second O site, O(2) is bonded in a linear geometry to one Al(1) and one Si(1) atom.
