AlPO4 is Rutile-derived structured and crystallizes in the orthorhombic Cmmm space group. Al(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form AlO6 octahedra that share corners with eight equivalent P(1)O6 octahedra and edges with two equivalent Al(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 48-50°. P(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form PO6 octahedra that share corners with eight equivalent Al(1)O6 octahedra and edges with two equivalent P(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 48-50°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to two equivalent Al(1) and one P(1) atom. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to one Al(1) and two equivalent P(1) atoms.
