RbGa2P2H3O10H2O crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional and consists of four water molecules and one RbGa2P2H3O10 framework. In the RbGa2P2H3O10 framework, Rb1+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Rb–O bond distances ranging from 2.87–3.24 Å. There are two inequivalent Ga3+ sites. In the first Ga3+ site, Ga3+ is bonded to six O2- atoms to form GaO6 octahedra that share corners with two equivalent GaO6 octahedra and corners with four PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 56–58°. There are a spread of Ga–O bond distances ranging from 1.94–2.16 Å. In the second Ga3+ site, Ga3+ is bonded to six O2- atoms to form GaO6 octahedra that share corners with two equivalent GaO6 octahedra, corners with four PO4 tetrahedra, and an edgeedge with one GaO6 octahedra. The corner-sharing octahedra tilt angles range from 56–58°. There are a spread of Ga–O bond distances ranging from 1.94–2.16 Å. There are two inequivalent P5+ sites. In the first P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with four GaO6 octahedra. The corner-sharing octahedra tilt angles range from 28–58°. There are a spread of P–O bond distances ranging from 1.53–1.57 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with four GaO6 octahedra. The corner-sharing octahedra tilt angles range from 37–50°. There are a spread of P–O bond distances ranging from 1.54–1.58 Å. There are three inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 1.01 Å. In the second H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. In the third H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 1.00 Å. There are ten inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Rb1+, one Ga3+, and one P5+ atom. In the second O2- site, O2- is bonded in a 2-coordinate geometry to one Ga3+ and one P5+ atom. In the third O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Rb1+, one Ga3+, and one P5+ atom. In the fourth O2- site, O2- is bonded in a distorted water-like geometry to one Ga3+ and two H1+ atoms. In the fifth O2- site, O2- is bonded in a 2-coordinate geometry to one Rb1+, one Ga3+, and one P5+ atom. In the sixth O2- site, O2- is bonded in a 2-coordinate geometry to one Rb1+, one Ga3+, and one P5+ atom.
