WTl6O12 crystallizes in the trigonal R-3 space group. W(1) is bonded in an octahedral geometry to six equivalent O(1) atoms. Tl(1) is bonded in a 7-coordinate geometry to three equivalent O(1) and four equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to one W(1) and three equivalent Tl(1) atoms. In the second O site, O(2) is bonded to four equivalent Tl(1) atoms to form a mixture of corner and edge-sharing OTl4 tetrahedra.
