KPH2SO3 crystallizes in the monoclinic Cm space group. K(1) is bonded in a 9-coordinate geometry to four equivalent S(1), one O(1), and four equivalent O(2) atoms. P(1) is bonded in a distorted tetrahedral geometry to one S(1), one O(1), and two equivalent O(2) atoms. H(1) is bonded in a linear geometry to one O(1) and one O(2) atom. S(1) is bonded in a distorted single-bond geometry to four equivalent K(1) and one P(1) atom. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to one K(1), one P(1), and two equivalent H(1) atoms. In the second O site, O(2) is bonded in a distorted bent 120 degrees geometry to two equivalent K(1), one P(1), and one H(1) atom.
KPH2SO3 crystallizes in the monoclinic Cm space group. K(1) is bonded in a 9-coordinate geometry to four equivalent S(1), one O(1), and four equivalent O(2) atoms. There are three shorter (3.36 Å) and one longer (3.56 Å) K(1)-S(1) bond length. The K(1)-O(1) bond length is 2.92 Å. There are two shorter (3.01 Å) and two longer (3.08 Å) K(1)-O(2) bond lengths. P(1) is bonded in a distorted tetrahedral geometry to one S(1), one O(1), and two equivalent O(2) atoms. The P(1)-S(1) bond length is 1.98 Å. The P(1)-O(1) bond length is 1.55 Å. Both P(1)-O(2) bond lengths are 1.60 Å. H(1) is bonded in a linear geometry to one O(1) and one O(2) atom. The H(1)-O(1) bond length is 1.50 Å. The H(1)-O(2) bond length is 1.04 Å.
