AlPO4 is low (alpha) Cristobalite-derived structured and crystallizes in the tetragonal I-4 space group. Al(1) is bonded to four equivalent O(1) atoms to form AlO4 tetrahedra that share corners with four equivalent P(1)O4 tetrahedra. P(1) is bonded to four equivalent O(1) atoms to form PO4 tetrahedra that share corners with four equivalent Al(1)O4 tetrahedra. O(1) is bonded in a bent 150 degrees geometry to one Al(1) and one P(1) atom.
AlPO4 is low (alpha) Cristobalite-derived structured and crystallizes in the tetragonal I-4 space group.
