description: RbGa2P5O16 crystallizes in the monoclinic Pc space group. The structure is three-dimensional. Rb1+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Rb–O bond distances ranging from 3.09–3.42 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 six PO4 tetrahedra. There are a spread of Ga–O bond distances ranging from 1.93–2.09 Å. In the second Ga3+ site, Ga3+ is bonded to six O2- atoms to form GaO6 octahedra that share corners with six PO4 tetrahedra. There are a spread of Ga–O bond distances ranging from 1.91–2.12 Å. There are five inequivalent P5+ sites. In the first P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with three GaO6 octahedra and a cornercorner with one PO4 tetrahedra.
