K is beta structured and crystallizes in the cubic P4_132 space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 2-coordinate geometry to two equivalent K(2) atoms. In the second K site, K(2) is bonded in a 6-coordinate geometry to three equivalent K(1) and three equivalent K(2) atoms.
K is beta structured and crystallizes in the cubic P4_132 space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 2-coordinate geometry to two equivalent K(2) atoms. Both K(1)-K(2) bond lengths are 4.64 Å. In the second K site, K(2) is bonded in a 6-coordinate geometry to three equivalent K(1) and three equivalent K(2) atoms. All K(2)-K(2) bond lengths are 4.29 Å.
