Abstract

K4S4O15(S)6 crystallizes in the orthorhombic Pbcn space group. The structure is three-dimensional and consists of twenty-four hydrogen sulfide molecules and one K4S4O15 framework. In the K4S4O15 framework, there are two inequivalent K1+ sites. In the first K1+ site, K1+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of K–O bond distances ranging from 2.83–3.27 Å. In the second K1+ site, K1+ is bonded in a 7-coordinate geometry to eight O2- atoms. There are a spread of K–O bond distances ranging from 2.78–3.41 Å. There are two inequivalent S+2.60+ sites. In the first S+2.60+ site, S+2.60+ is bonded in a trigonal non-coplanar geometry to three O2- atoms. There is one shorter (1.46 Å) and two longer (1.47 Å) S–O bond length. In the second S+2.60+ site, S+2.60+ is bonded in a trigonal non-coplanar geometry to three O2- atoms. There is two shorter (1.47 Å) and one longer (1.48 Å) S–O bond length. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to two K1+ and one S+2.60+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to three K1+ and one S+2.60+ atom. In the third O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent K1+ and one S+2.60+ atom. In the fourth O2- site, O2- is bonded in a water-like geometry to two K1+ atoms. In the fifth O2- site, O2- is bonded in a distorted single-bond geometry to two K1+ and one S+2.60+ atom. In the sixth O2- site, O2- is bonded in a distorted water-like geometry to two equivalent K1+ atoms. In the seventh O2- site, O2- is bonded in a single-bond geometry to one S+2.60+ atom. In the eighth O2- site, O2- is bonded in a distorted single-bond geometry to three K1+ and one S+2.60+ atom.
