The crystal structure described by RbPO3 crystallizes in the monoclinic P2_1/c space group. Rb(1) is bonded in a 7-coordinate geometry to one O(3), three equivalent O(1), and three equivalent O(2) atoms. P(1) is bonded to one O(1), one O(2), and two equivalent O(3) atoms to form corner-sharing PO4 tetrahedra. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to three equivalent Rb(1) and one P(1) atom. 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. In the third O site, O(3) is bonded in a distorted bent 120 degrees geometry to one Rb(1) and two equivalent P(1) atoms. is represented by the CIF card [CIF]
