Rb3P3O10 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are three inequivalent Rb sites. In the first Rb site, Rb is bonded in a 7-coordinate geometry to seven O atoms. There are a spread of Rb–O bond distances ranging from 2.89–3.14 Å. In the second Rb site, Rb is bonded in a 6-coordinate geometry to six O atoms. There are a spread of Rb–O bond distances ranging from 2.87–3.21 Å. In the third Rb site, Rb is bonded in a 7-coordinate geometry to seven O atoms. There are a spread of Rb–O bond distances ranging from 2.92–3.10 Å. There are three inequivalent P sites. In the first P site, P is bonded to four O atoms to form corner-sharing PO4 tetrahedra. There are a spread of P–O bond distances ranging from 1.49–1.65 Å. In the second P site, P is bonded to four O atoms to form corner-sharing PO4 tetrahedra. There are a spread of P–O bond distances ranging from 1.50–1.63 Å. In the third P site, P is bonded to four O atoms to form corner-sharing PO4 tetrahedra. There is two shorter (1.49 Å) and two longer (1.65 Å) P–O bond length. There are ten inequivalent O sites. In the first O site, O is bonded in a distorted single-bond geometry to two Rb and one P atom. In the second O site, O is bonded in a bent 120 degrees geometry to two P atoms. In the third O site, O is bonded in a distorted bent 120 degrees geometry to one Rb and two P atoms. In the fourth O site, O is bonded in a distorted single-bond geometry to two Rb and one P atom. In the fifth O site, O is bonded in a distorted single-bond geometry to three Rb and one P atom. In the sixth O site, O is bonded in a distorted single-bond geometry to two equivalent Rb and one P atom. In the seventh O site, O is bonded in a distorted single-bond geometry to three Rb and one P atom. In the eighth O site, O is bonded in a distorted bent 120 degrees geometry to one Rb and two P atoms. In the ninth O site, O is bonded in a distorted single-bond geometry to three Rb and one P atom. In the tenth O site, O is bonded in a 4-coordinate geometry to three Rb atoms.
