The compound described by Ho6WO12 crystallizes in the trigonal R-3 space group. Ho(1) is bonded in a 7-coordinate geometry to three equivalent O(2) and four equivalent O(1) atoms. W(1) is bonded in an octahedral geometry to six equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(2) is bonded in a 4-coordinate geometry to three equivalent Ho(1) and one W(1) atom. In the second O site, O(1) is bonded to four equivalent Ho(1) atoms to form a mixture of edge and corner-sharing OHo4 tetrahedra. is represented by the CIF card [CIF]
