The structure described by Rb3GaP6(HO3)6 crystallizes in the trigonal R-3 space group. Rb(1) is bonded to two equivalent O(1), two equivalent O(3), and four equivalent O(2) atoms to form RbO8 hexagonal bipyramids that share corners with four equivalent Rb(1)O8 hexagonal bipyramids, corners with two equivalent Ga(1)O6 octahedra, corners with four equivalent P(1)HO3 tetrahedra, and edges with two equivalent P(1)HO3 tetrahedra. The corner-sharing octahedral tilt angles are 53°. Ga(1) is bonded to six equivalent O(1) atoms to form GaO6 octahedra that share corners with six equivalent Rb(1)O8 hexagonal bipyramids and corners with six equivalent P(1)HO3 tetrahedra. P(1) is bonded to one H(1), one O(1), one O(2), and one O(3) atom to form distorted PHO3 tetrahedra that share corners with two equivalent Rb(1)O8 hexagonal bipyramids,  a cornercorner with one Ga(1)O6 octahedra, and  an edgeedge with one Rb(1)O8 hexagonal bipyramid. The corner-sharing octahedral tilt angles are 44°. H(1) is bonded in a single-bond geometry to one P(1) atom. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted bent 150 degrees geometry to one Rb(1), one Ga(1), and one P(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to two equivalent Rb(1) and one P(1) atom. In the third O site, O(3) is bonded in a distorted single-bond geometry to one Rb(1) and one P(1) atom. is represented by the CIF card [CIF]
