K crystallizes in the orthorhombic Pnma space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 8-coordinate geometry to two equivalent K(1) and six equivalent K(2) atoms. In the second K site, K(2) is bonded in a 8-coordinate geometry to two equivalent K(2) and six equivalent K(1) atoms.
K crystallizes in the orthorhombic Pnma space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 8-coordinate geometry to two equivalent K(1) and six equivalent K(2) atoms. Both K(1)-K(1) bond lengths are 4.49 Å. There are a spread of K(1)-K(2) bond distances ranging from 4.48-4.78 Å. In the second K site, K(2) is bonded in a 8-coordinate geometry to two equivalent K(2) and six equivalent K(1) atoms. Both K(2)-K(2) bond lengths are 4.54 Å.
