The material structure described by KMnHP3O10 crystallizes in the monoclinic C2/c space group. K(1) is bonded in a 6-coordinate geometry to two equivalent O(1), two equivalent O(3), and two equivalent O(5) atoms. Mn(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form MnO6 octahedra that share corners with two equivalent P(1)O4 tetrahedra and corners with four equivalent P(2)O4 tetrahedra. There are two inequivalent P sites. In the first P site, P(1) is bonded to two equivalent O(3) and two equivalent O(4) atoms to form PO4 tetrahedra that share corners with two equivalent Mn(1)O6 octahedra and corners with two equivalent P(2)O4 tetrahedra. The corner-sharing octahedral tilt angles are 50°. In the second P site, P(2) is bonded to one O(1), one O(2), one O(4), and one O(5) atom to form PO4 tetrahedra that share corners with two equivalent Mn(1)O6 octahedra and  a cornercorner with one P(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 35-47°. H(1) is bonded in a linear geometry to two equivalent O(5) atoms. There are five inequivalent O sites. In the first O site, O(3) is bonded in a 2-coordinate geometry to one K(1), one Mn(1), and one P(1) atom. In the second O site, O(4) is bonded in a bent 120 degrees geometry to one P(1) and one P(2) atom. In the third O site, O(5) is bonded in a distorted bent 120 degrees geometry to one K(1), one P(2), and one H(1) atom. In the fourth O site, O(1) is bonded in a distorted bent 150 degrees geometry to one K(1), one Mn(1), and one P(2) atom. In the fifth O site, O(2) is bonded in a distorted bent 120 degrees geometry to one Mn(1) and one P(2) atom. is represented by the CIF card [CIF]
