The crystal structure described by Al5Sb3O16 is Hydrophilite-derived structured and crystallizes in the monoclinic C2/m space group. There are two inequivalent Al sites. In the first Al site, Al(1) is bonded to one O(2), one O(3), one O(4), one O(5), and two equivalent O(1) atoms to form AlO6 octahedra that share corners with two equivalent Sb(2)O6 octahedra, corners with four equivalent Sb(1)O6 octahedra,  an edgeedge with one Al(2)O6 octahedra, and edges with two equivalent Al(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 48-52°. In the second Al site, Al(2) is bonded to two equivalent O(3) and four equivalent O(2) atoms to form AlO6 octahedra that share corners with four equivalent Sb(1)O6 octahedra and edges with four equivalent Al(1)O6 octahedra. The corner-sharing octahedral tilt angles are 53°. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(4) atoms to form SbO6 octahedra that share corners with two equivalent Al(2)O6 octahedra, corners with eight equivalent Al(1)O6 octahedra, and  an edgeedge with one Sb(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 48-53°. In the second Sb site, Sb(2) is bonded to two equivalent O(5) and four equivalent O(4) atoms to form SbO6 octahedra that share corners with eight equivalent Al(1)O6 octahedra and edges with two equivalent Sb(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 50-52°. There are five 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 Sb(1) atom. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to one Al(1), one Al(2), and one Sb(1) atom. In the third O site, O(3) is bonded in a trigonal non-coplanar geometry to one Al(2) and two equivalent Al(1) atoms. In the fourth O site, O(4) is bonded in a distorted trigonal planar geometry to one Al(1), one Sb(1), and one Sb(2) atom. In the fifth O site, O(5) is bonded in a trigonal planar geometry to two equivalent Al(1) and one Sb(2) atom. is represented by the CIF card [CIF]
