Tl2WO4 crystallizes in the trigonal P-3m1 space group. W(1) is bonded in a tetrahedral geometry to one O(2) and three equivalent O(1) atoms. There are three inequivalent Tl sites. In the first Tl site, Tl(1) is bonded in a single-bond geometry to one O(2) atom. In the second Tl site, Tl(2) is bonded in a 6-coordinate geometry to six equivalent O(1) atoms. In the third Tl site, Tl(3) is bonded in a 6-coordinate geometry to six equivalent O(1) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to one W(1), one Tl(2), and one Tl(3) atom. In the second O site, O(2) is bonded in a linear geometry to one W(1) and one Tl(1) atom.
