The material described by TlBi(WO4)2 crystallizes in the monoclinic C2/c space group. The structure consists of four 7440-28-0 atoms inside a Bi(WO4)2 framework. In the Bi(WO4)2 framework, W(1) is bonded to one O(2), one O(4), two equivalent O(1), and two equivalent O(3) atoms to form WO6 octahedra that share corners with two equivalent W(1)O6 octahedra, corners with four equivalent Bi(1)O6 pentagonal pyramids, and  an edgeedge with one W(1)O6 octahedra. The corner-sharing octahedral tilt angles are 41°. Bi(1) is bonded to two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms to form distorted BiO6 pentagonal pyramids that share corners with eight equivalent W(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 27-68°. 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 W(1) and one Bi(1) atom. In the third O site, O(3) is bonded in a distorted trigonal non-coplanar geometry to two equivalent W(1) and one Bi(1) atom. In the fourth O site, O(4) is bonded in a bent 150 degrees geometry to one W(1) and one Bi(1) atom. is represented by the CIF file [CIF]
