Abstract

SK1 is alpha boron-derived structured and crystallizes in the hexagonal P-62m space group. The structure is three-dimensional. there are two inequivalent K1+ sites. In the first K1+ site, K1+ is bonded in a 6-coordinate geometry to six S1- atoms. There are two shorter (3.25 Å) and four longer (3.35 Å) K–S bond lengths. In the second K1+ site, K1+ is bonded in a 6-coordinate geometry to six S1- atoms. There are four shorter (3.17 Å) and two longer (3.25 Å) K–S bond lengths. There are two inequivalent S1- sites. In the first S1- site, S1- is bonded in a 7-coordinate geometry to six K1+ and one S1- atom. The S–S bond length is 2.13 Å. In the second S1- site, S1- is bonded in a 7-coordinate geometry to six K1+ and one S1- atom. The S–S bond length is 2.14 Å.
