The compound described by RbMnHP3O10 crystallizes in the monoclinic C2/c space group. Rb(1) is bonded to two equivalent O(1), two equivalent O(2), two equivalent O(4), and two equivalent O(5) atoms to form distorted RbO8 hexagonal bipyramids that share corners with two equivalent Mn(1)O6 octahedra, corners with two equivalent P(2)O4 tetrahedra, edges with two equivalent Mn(1)O6 octahedra,  an edgeedge with one P(1)O4 tetrahedra, and edges with two equivalent P(2)O4 tetrahedra. The corner-sharing octahedral tilt angles are 57°. Mn(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(4) atoms to form MnO6 octahedra that share corners with two equivalent Rb(1)O8 hexagonal bipyramids, corners with two equivalent P(1)O4 tetrahedra, corners with four equivalent P(2)O4 tetrahedra, and edges with two equivalent Rb(1)O8 hexagonal bipyramids. There are two inequivalent P sites. In the first P site, P(1) is bonded to two equivalent O(1) and two equivalent O(3) atoms to form PO4 tetrahedra that share corners with two equivalent Mn(1)O6 octahedra, corners with two equivalent P(2)O4 tetrahedra, and  an edgeedge with one Rb(1)O8 hexagonal bipyramid. The corner-sharing octahedral tilt angles are 49°. In the second P site, P(2) is bonded to one O(2), one O(3), one O(4), and one O(5) atom to form PO4 tetrahedra that share  a cornercorner with one Rb(1)O8 hexagonal bipyramid, corners with two equivalent Mn(1)O6 octahedra,  a cornercorner with one P(1)O4 tetrahedra, and  an edgeedge with one Rb(1)O8 hexagonal bipyramid. The corner-sharing octahedral tilt angles range from 34-48°. 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 bent 120 degrees geometry to one P(1) and one P(2) atom. In the second O site, O(4) is bonded in a distorted bent 120 degrees geometry to one Rb(1), one Mn(1), and one P(2) atom. In the third O site, O(5) is bonded in a distorted bent 120 degrees geometry to one Rb(1), one P(2), and one H(1) atom. In the fourth O site, O(1) is bonded in a 2-coordinate geometry to one Rb(1), one Mn(1), and one P(1) atom. In the fifth O site, O(2) is bonded in a distorted bent 150 degrees geometry to one Rb(1), one Mn(1), and one P(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
