K(WO3)6 crystallizes in the trigonal P-31m space group. K(1) is bonded to twelve equivalent O(3) atoms to form KO12 cuboctahedra that share edges with twelve equivalent W(1)O6 octahedra. W(1) is bonded to one O(1), one O(2), and four equivalent O(3) atoms to form WO6 octahedra that share corners with six equivalent W(1)O6 octahedra and edges with two equivalent K(1)O12 cuboctahedra. The corner-sharing octahedral tilt angles range from 0-29°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a linear geometry to two equivalent W(1) atoms. In the second O site, O(2) is bonded in a linear geometry to two equivalent W(1) atoms. In the third O site, O(3) is bonded in a bent 150 degrees geometry to one K(1) and two equivalent W(1) atoms.
K(WO3)6 crystallizes in the trigonal P-31m space group. K(1) is bonded to twelve equivalent O(3) atoms to form KO12 cuboctahedra that share edges with twelve equivalent W(1)O6 octahedra. All K(1)-O(3) bond lengths are 3.31 Å. W(1) is bonded to one O(1), one O(2), and four equivalent O(3) atoms to form WO6 octahedra that share corners with six equivalent W(1)O6 octahedra and edges with two equivalent K(1)O12 cuboctahedra. The corner-sharing octahedral tilt angles range from 0-29°. The W(1)-O(1) bond length is 1.91 Å. The W(1)-O(2) bond length is 1.90 Å. There are two shorter (1.83 Å) and two longer (2.02 Å) W(1)-O(3) bond lengths. There are three inequivalent O sites. In the first O site, O(1) is bonded in a linear geometry to two equivalent W(1) atoms. In the second O site, O(2) is bonded in a linear geometry to two equivalent W(1) atoms. In the third O site, O(3) is bonded in a bent 150 degrees geometry to one K(1) and two equivalent W(1) atoms.
