Y(WO4)2Tl crystallizes in the monoclinic C2/c space group. The structure consists of four 7440-28-0 atoms inside a Y(WO4)2 framework. In the Y(WO4)2 framework, Y(1) is bonded in a 6-coordinate geometry to two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms. W(1) is bonded to one O(2), one O(4), two equivalent O(1), and two equivalent O(3) atoms to form a mixture of corner and edge-sharing WO6 octahedra. The corner-sharing octahedral tilt angles are 42°. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted bent 150 degrees geometry to two equivalent W(1) atoms. In the second O site, O(2) is bonded in a 2-coordinate geometry to one Y(1) and one W(1) atom. In the third O site, O(3) is bonded in a distorted trigonal non-coplanar geometry to one Y(1) and two equivalent W(1) atoms. In the fourth O site, O(4) is bonded in a bent 150 degrees geometry to one Y(1) and one W(1) atom.

In the Y(WO4)2 framework, Y(1) is bonded in a 6-coordinate geometry to two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms. Both Y(1)-O(2) bond lengths are 2.33 Å. Both Y(1)-O(3) bond lengths are 2.32 Å. Both Y(1)-O(4) bond lengths are 2.29 Å. W(1) is bonded to one O(2), one O(4), two equivalent O(1), and two equivalent O(3) atoms to form a mixture of corner and edge-sharing WO6 octahedra. The corner-sharing octahedral tilt angles are 42°. The W(1)-O(2) bond length is 1.86 Å. The W(1)-O(4) bond length is 1.83 Å. There is one shorter (1.89 Å) and one longer (2.12 Å) W(1)-O(1) bond length. There is one shorter (2.02 Å) and one longer (2.12 Å) W(1)-O(3) bond length. There are four inequivalent O sites.
