The material structure described by YbTl(WO4)2 crystallizes in the monoclinic C2/c space group. Yb(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 distorted edge and corner-sharing WO6 octahedra. The corner-sharing octahedral tilt angles are 40°. Tl(1) is bonded in a 6-coordinate geometry to two equivalent O(1), two equivalent O(3), and two equivalent O(4) atoms. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal non-coplanar geometry to two equivalent W(1) and one Tl(1) atom. In the second O site, O(2) is bonded in a distorted bent 150 degrees geometry to one Yb(1) and one W(1) atom. In the third O site, O(3) is bonded to one Yb(1), two equivalent W(1), and one Tl(1) atom to form a mixture of distorted edge and corner-sharing OYbTlW2 tetrahedra. In the fourth O site, O(4) is bonded in a distorted bent 150 degrees geometry to one Yb(1), one W(1), and one Tl(1) atom. is represented by the CIF file [CIF]
