AlPO4 is quartz (alpha)-derived structured and crystallizes in the monoclinic C2/c space group. There are two inequivalent Al sites. In the first Al site, Al(1) is bonded to one O(1), one O(5), one O(6), and one O(7) atom to form AlO4 tetrahedra that share corners with two equivalent P(1)O4 tetrahedra and corners with two equivalent P(2)O4 tetrahedra. The Al(1)-O(1) bond length is 1.86 Å. The Al(1)-O(5) bond length is 1.86 Å. The Al(1)-O(6) bond length is 1.85 Å. The Al(1)-O(7) bond length is 1.87 Å. In the second Al site, Al(2) is bonded to one O(2), one O(3), one O(4), and one O(8) atom to form AlO4 tetrahedra that share corners with two equivalent P(1)O4 tetrahedra and corners with two equivalent P(2)O4 tetrahedra. The Al(2)-O(2) bond length is 1.88 Å. The Al(2)-O(3) bond length is 1.86 Å. The Al(2)-O(4) bond length is 1.86 Å. The Al(2)-O(8) bond length is 1.82 Å. There are two inequivalent P sites. In the first P site, P(1) is bonded to one O(3), one O(4), one O(5), and one O(7) atom to form PO4 tetrahedra that share corners with two equivalent Al(1)O4 tetrahedra and corners with two equivalent Al(2)O4 tetrahedra. The P(1)-O(3) bond length is 1.53 Å. The P(1)-O(4) bond length is 1.50 Å. The P(1)-O(5) bond length is 1.53 Å. The P(1)-O(7) bond length is 1.50 Å. In the second P site, P(2) is bonded to one O(1), one O(2), one O(6), and one O(8) atom to form PO4 tetrahedra that share corners with two equivalent Al(1)O4 tetrahedra and corners with two equivalent Al(2)O4 tetrahedra. The P(2)-O(1) bond length is 1.50 Å. The P(2)-O(2) bond length is 1.51 Å. The P(2)-O(6) bond length is 1.52 Å. The P(2)-O(8) bond length is 1.50 Å. There are eight inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to one Al(1) and one P(2) atom. In the second O site, O(2) is bonded in a bent 150 degrees geometry to one Al(2) and one P(2) atom. In the third O site, O(3) is bonded in a bent 120 degrees geometry to one Al(2) and one P(1) atom. In the fourth O site, O(4) is bonded in a bent 150 degrees geometry to one Al(2) and one P(1) atom. In the fifth O site, O(5) is bonded in a bent 150 degrees geometry to one Al(1) and one P(1) atom. In the sixth O site, O(6) is bonded in a bent 150 degrees geometry to one Al(1) and one P(2) atom. In the seventh O site, O(7) is bonded in a bent 150 degrees geometry to one Al(1) and one P(1) atom. In the eighth O site, O(8) is bonded in a bent 150 degrees geometry to one Al(2) and one P(2) atom. Linkers: 16 [O]P([O])([O])=O. Metal clusters: 16 [Al].
