The structure described by AlSn(WO4)2 crystallizes in the triclinic P1 space group. There are two inequivalent W sites. In the first W site, W(1) is bonded to one O(1), one O(2), one O(3), one O(4), one O(7), and one O(8) atom to form distorted WO6 octahedra that share  a cornercorner with one W(2)O7 pentagonal bipyramid,  a cornercorner with one Al(1)O5 tetrahedra, edges with two equivalent W(2)O7 pentagonal bipyramids, and  an edgeedge with one Al(1)O5 tetrahedra. In the second W site, W(2) is bonded to one O(2), one O(3), one O(4), one O(5), one O(6), one O(7), and one O(8) atom to form distorted WO7 pentagonal bipyramids that share  a cornercorner with one W(1)O6 octahedra, corners with two equivalent Al(1)O5 tetrahedra, edges with two equivalent W(1)O6 octahedra, and  an edgeedge with one Al(1)O5 tetrahedra. The corner-sharing octahedral tilt angles are 30°. Al(1) is bonded to one O(1), one O(4), one O(5), one O(6), and one O(7) atom to form distorted AlO5 tetrahedra that share  a cornercorner with one W(1)O6 octahedra, corners with two equivalent W(2)O7 pentagonal bipyramids,  an edgeedge with one W(1)O6 octahedra, and  an edgeedge with one W(2)O7 pentagonal bipyramid. The corner-sharing octahedral tilt angles are 15°. Sn(1) is bonded in a 7-coordinate geometry to one O(2), one O(3), one O(4), one O(5), one O(6), one O(7), and one O(8) atom. There are eight inequivalent O sites. In the first O site, O(1) is bonded in a linear geometry to one W(1) and one Al(1) atom. In the second O site, O(2) is bonded in a distorted bent 150 degrees geometry to one W(1), one W(2), and one Sn(1) atom. In the third O site, O(3) is bonded in a 3-coordinate geometry to one W(1), one W(2), and one Sn(1) atom. In the fourth O site, O(4) is bonded in a 4-coordinate geometry to one W(1), one W(2), one Al(1), and one Sn(1) atom. In the fifth O site, O(5) is bonded in a 3-coordinate geometry to one W(2), one Al(1), and one Sn(1) atom. In the sixth O site, O(6) is bonded in a trigonal planar geometry to one W(2), one Al(1), and one Sn(1) atom. In the seventh O site, O(7) is bonded in a distorted trigonal pyramidal geometry to one W(1), one W(2), one Al(1), and one Sn(1) atom. In the eighth O site, O(8) is bonded in a trigonal non-coplanar geometry to one W(1), one W(2), and one Sn(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
