AlSn(WO4)2 is Hydrophilite-derived structured and crystallizes in the monoclinic P2/c space group. W(1) is bonded to one O(1), one O(3), two equivalent O(2), and two equivalent O(4) atoms to form WO6 octahedra that share corners with four equivalent Al(1)O6 octahedra, corners with four equivalent Sn(1)O6 octahedra, and edges with two equivalent W(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 46-58°. Al(1) is bonded to two equivalent O(1), two equivalent O(3), and two equivalent O(4) atoms to form AlO6 octahedra that share corners with eight equivalent W(1)O6 octahedra and edges with two equivalent Sn(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 46-52°. Sn(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form SnO6 octahedra that share corners with eight equivalent W(1)O6 octahedra and edges with two equivalent Al(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 47-58°. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to one W(1), one Al(1), and one Sn(1) atom. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to two equivalent W(1) and one Sn(1) atom. In the third O site, O(3) is bonded in a distorted trigonal planar geometry to one W(1), one Al(1), and one Sn(1) atom. In the fourth O site, O(4) is bonded in a distorted trigonal planar geometry to two equivalent W(1) and one Al(1) atom.
