Ba(WO3)6 crystallizes in the trigonal P31m space group. Ba(1) is bonded in a 6-coordinate geometry to six equivalent O(4) atoms. There are two inequivalent W sites. In the first W site, W(1) is bonded to one O(1), one O(2), and four equivalent O(4) atoms to form corner-sharing WO6 octahedra. The corner-sharing octahedral tilt angles range from 0-32°. In the second W site, W(2) is bonded to one O(1), one O(2), and four equivalent O(3) atoms to form corner-sharing WO6 octahedra. The corner-sharing octahedral tilt angles range from 0-30°. There are four inequivalent O sites. In the first O site, O(1) is bonded in a linear geometry to one W(1) and one W(2) atom. In the second O site, O(2) is bonded in a linear geometry to one W(1) and one W(2) atom. In the third O site, O(3) is bonded in a bent 150 degrees geometry to two equivalent W(2) atoms. In the fourth O site, O(4) is bonded in a distorted bent 150 degrees geometry to one Ba(1) and two equivalent W(1) atoms.
Ba(WO3)6 crystallizes in the trigonal P31m space group. Ba(1) is bonded in a 6-coordinate geometry to six equivalent O(4) atoms. All Ba(1)-O(4) bond lengths are 3.00 Å. There are two inequivalent W sites. In the first W site, W(1) is bonded to one O(1), one O(2), and four equivalent O(4) atoms to form corner-sharing WO6 octahedra. The corner-sharing octahedral tilt angles range from 0-32°. The W(1)-O(1) bond length is 1.89 Å. The W(1)-O(2) bond length is 1.91 Å. There are two shorter (1.90 Å) and two longer (1.95 Å) W(1)-O(4) bond lengths. In the second W site, W(2) is bonded to one O(1), one O(2), and four equivalent O(3) atoms to form corner-sharing WO6 octahedra. The corner-sharing octahedral tilt angles range from 0-30°.
