The material described by Gd6WO12 crystallizes in the trigonal R-3 space group. Gd(1) is bonded in a 7-coordinate geometry to three equivalent O(1) and four equivalent O(2) atoms. W(1) is bonded in an octahedral geometry to six equivalent O(1) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to three equivalent Gd(1) and one W(1) atom. In the second O site, O(2) is bonded to four equivalent Gd(1) atoms to form a mixture of corner and edge-sharing OGd4 tetrahedra. is represented by the CIF file [CIF]
