KHSO4 crystallizes in the orthorhombic Pbca space group. The structure is three-dimensional. there are two inequivalent K1+ sites. In the first K1+ site, K1+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of K–O bond distances ranging from 2.79–3.11 Å. In the second K1+ site, K1+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of K–O bond distances ranging from 2.79–3.08 Å. There are two inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a linear geometry to two O2- atoms. There is one shorter (1.03 Å) and one longer (1.53 Å) H–O bond length. In the second H1+ site, H1+ is bonded in a linear geometry to two O2- atoms. There is one shorter (1.02 Å) and one longer (1.59 Å) H–O bond length. There are two inequivalent S6+ sites. In the first S6+ site, S6+ is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of S–O bond distances ranging from 1.46–1.60 Å. In the second S6+ site, S6+ is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of S–O bond distances ranging from 1.46–1.60 Å. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a 2-coordinate geometry to two K1+, one H1+, and one S6+ atom. In the second O2- site, O2- is bonded in a 4-coordinate geometry to two K1+, one H1+, and one S6+ atom. In the third O2- site, O2- is bonded in a distorted bent 120 degrees geometry to two K1+, one H1+, and one S6+ atom. In the fourth O2- site, O2- is bonded in a 2-coordinate geometry to two K1+, one H1+, and one S6+ atom. In the fifth O2- site, O2- is bonded in a distorted single-bond geometry to two K1+ and one S6+ atom. In the sixth O2- site, O2- is bonded in a distorted single-bond geometry to three K1+ and one S6+ atom. In the seventh O2- site, O2- is bonded in a distorted single-bond geometry to two K1+ and one S6+ atom. In the eighth O2- site, O2- is bonded in a distorted single-bond geometry to three K1+ and one S6+ atom.
