There are a spread of P–O bond distances ranging from 1.53–1.62 Å. There are four inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a distorted linear geometry to one K1+ and two O2- atoms. There is one shorter (1.02 Å) and one longer (1.61 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 (1.57 Å) H–O bond length. In the third H1+ site, H1+ is bonded in a linear geometry to one K1+ and two O2- atoms. There is one shorter (1.04 Å) and one longer (1.46 Å) H–O bond length. In the fourth H1+ site, H1+ is bonded in a linear geometry to two O2- atoms. There is one shorter (1.05 Å) and one longer (1.46 Å) H–O bond length. There are twelve inequivalent O2- sites. In the first O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent K1+, one Mn2+, and one P5+ atom. In the second O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one K1+, one Mn2+, one P5+, and one H1+ atom. In the third O2- site, O2- is bonded in a 2-coordinate geometry to two K1+, one P5+, and one H1+ atom. In the fourth O2- site, O2- is bonded in a 1-coordinate geometry to one K1+, two Mn2+, and one P5+ atom. In the fifth O2- site, O2- is bonded in a 2-coordinate geometry to two K1+, one Mn2+, and one P5+ atom. In the sixth O2- site, O2- is bonded in a 2-coordinate geometry to two K1+, one P5+, and one H1+ atom. In the seventh O2- site, O2- is bonded in a 3-coordinate geometry to one K1+, one P5+, and two H1+ atoms. In the eighth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to two K1+, one P5+, and one H1+ atom. In the ninth O2- site, O2- is bonded in a 1-coordinate geometry to one K1+, two Mn2+, and one P5+ atom. In the tenth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one K1+, one P5+, and one H1+ atom. In the eleventh O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Mn2+ and one P5+ atom. In the twelfth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one K1+, one P5+, and one H1+ atom.
