K is alpha La structured and crystallizes in the hexagonal P6_3/mmc space group. There are two inequivalent K sites. In the first K site, K(1) is bonded to six equivalent K(1) and six equivalent K(2) atoms to form a mixture of face, corner, and edge-sharing KK12 cuboctahedra. In the second K site, K(2) is bonded to six equivalent K(1) and six equivalent K(2) atoms to form a mixture of face, corner, and edge-sharing KK12 cuboctahedra.

In the first K site, K(1) is bonded to six equivalent K(1) and six equivalent K(2) atoms to form a mixture of face, corner, and edge-sharing KK12 cuboctahedra. All K(1)-K(1) bond lengths are 4.77 Å. All K(1)-K(2) bond lengths are 4.79 Å. In the second K site, K(2) is bonded to six equivalent K(1) and six equivalent K(2) atoms to form a mixture of face, corner, and edge-sharing KK12 cuboctahedra. All K(2)-K(2) bond lengths are 4.77 Å.
