Abstract

KCF3SO3 crystallizes in the monoclinic P2_1 space group. The structure is three-dimensional and consists of six fluoroform molecules and one KSO3 framework. In the KSO3 framework, there are three inequivalent K1+ sites. In the first K1+ site, K1+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of K–O bond distances ranging from 2.65–3.03 Å. In the second K1+ site, K1+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of K–O bond distances ranging from 2.75–2.83 Å. In the third K1+ site, K1+ is bonded in a 10-coordinate geometry to ten O2- atoms. There are a spread of K–O bond distances ranging from 2.79–3.34 Å. There are three inequivalent S4+ sites. In the first S4+ site, S4+ 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 S4+ site, S4+ 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 third S4+ site, S4+ is bonded in a trigonal non-coplanar geometry to three O2- atoms. There is two shorter (1.46 Å) and one longer (1.47 Å) S–O bond length. There are nine inequivalent O2- sites. In the first O2- site, O2- is bonded in a 1-coordinate geometry to two K1+ and one S4+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to three K1+ and one S4+ atom. In the third O2- site, O2- is bonded in a 1-coordinate geometry to one K1+ and one S4+ atom. In the fourth O2- site, O2- is bonded in a distorted single-bond geometry to three K1+ and one S4+ atom. In the fifth O2- site, O2- is bonded in a 1-coordinate geometry to two K1+ and one S4+ atom. In the sixth O2- site, O2- is bonded in a distorted single-bond geometry to one K1+ and one S4+ atom. In the seventh O2- site, O2- is bonded in a distorted single-bond geometry to three K1+ and one S4+ atom. In the eighth O2- site, O2- is bonded in a distorted single-bond geometry to three K1+ and one S4+ atom. In the ninth O2- site, O2- is bonded in a single-bond geometry to two equivalent K1+ and one S4+ atom.
