The structure described by RbPO3 crystallizes in the orthorhombic Pnma space group. Rb(1) is bonded in a 6-coordinate geometry to six equivalent O(2) atoms. P(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form corner-sharing PO4 tetrahedra. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted bent 120 degrees geometry to two equivalent P(1) atoms. In the second O site, O(2) is bonded in a distorted single-bond geometry to three equivalent Rb(1) and one P(1) atom. is represented by the CIF file [CIF]
