RbPNO2 crystallizes in the trigonal R-3 space group. Rb(1) is bonded in a 9-coordinate geometry to two equivalent N(1), three equivalent O(1), and four equivalent O(2) atoms. P(1) is bonded to two equivalent N(1), one O(1), and one O(2) atom to form corner-sharing PN2O2 tetrahedra. N(1) is bonded in a distorted bent 120 degrees geometry to two equivalent Rb(1) and two equivalent P(1) atoms. There are two 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 single-bond geometry to four equivalent Rb(1) and one P(1) atom.
RbPNO2 crystallizes in the trigonal R-3 space group. Rb(1) is bonded in a 9-coordinate geometry to two equivalent N(1), three equivalent O(1), and four equivalent O(2) atoms.
