The material structure described by SK1 is alpha boron-derived structured and crystallizes in the hexagonal P-62m space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 6-coordinate geometry to two equivalent S(2) and four equivalent S(1) atoms. In the second K site, K(2) is bonded in a 6-coordinate geometry to two equivalent S(2) and four equivalent S(1) atoms. There are two inequivalent S sites. In the first S site, S(2) is bonded to three equivalent K(1), three equivalent K(2), and one S(2) atom to form a mixture of distorted corner, edge, and face-sharing SK6S pentagonal bipyramids. In the second S site, S(1) is bonded to three equivalent K(1), three equivalent K(2), and one S(1) atom to form a mixture of distorted corner, edge, and face-sharing SK6S pentagonal bipyramids. is represented by the CIF file [CIF]
