Materials Data on KHS by Materials Project
SKH1 crystallizes in the trigonal R3m space group. The structure is three-dimensional. K1+ is bonded in a 6-coordinate geometry to three equivalent H1+ and six equivalent S2- atoms. All K–H bond lengths are 2.91 Å. There are three shorter (3.30 Å) and three longer (3.35 Å) K–S bond lengths. H1+ is bonded in a distorted single-bond geometry to three equivalent K1+ and one S2- atom. The H–S bond length is 1.35 Å. S2- is bonded in a single-bond geometry to six equivalent K1+ and one H1+ atom.
