The structure described by Al4P3(HO5)3 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(3), one O(5), one O(6), and two equivalent O(8) atoms to form AlO6 octahedra that share  a cornercorner with one Al(2)O6 octahedra, corners with two equivalent Al(1)O6 octahedra,  a cornercorner with one P(1)O4 tetrahedra, corners with three equivalent P(2)O4 tetrahedra, and  a faceface with one Al(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 51-52°. In the second Al site, Al(2) is bonded to one O(1), one O(2), one O(4), one O(5), one O(7), and one O(8) atom to form AlO6 octahedra that share  a cornercorner with one Al(1)O6 octahedra,  a cornercorner with one Al(2)O6 octahedra, corners with two equivalent P(1)O4 tetrahedra, corners with two equivalent P(2)O4 tetrahedra, and  a faceface with one Al(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 42-51°. There are two inequivalent P sites.

The corner-sharing octahedral tilt angles range from 22-50°. There are two inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one O(7) atom. In the second H site, H(2) is bonded in a single-bond geometry to one O(8) atom. There are eight inequivalent O sites. In the first O site, O(7) is bonded in a distorted trigonal planar geometry to two equivalent Al(2) and one H(1) atom. In the second O site, O(8) is bonded in a distorted single-bond geometry to one Al(2), two equivalent Al(1), and one H(2) atom.
