Rb5NO5 crystallizes in the monoclinic Pm space group. There are three inequivalent Rb sites. In the first Rb site, Rb(1) is bonded in a distorted trigonal planar geometry to one Rb(2) and three equivalent O(4) atoms. In the second Rb site, Rb(2) is bonded in a 8-coordinate geometry to two equivalent Rb(1) and six equivalent Rb(2) atoms. In the third Rb site, Rb(3) is bonded in a 4-coordinate geometry to one N(1), one O(3), one O(4), and two equivalent O(2) atoms. N(1) is bonded in a distorted tetrahedral geometry to two equivalent Rb(3), one O(1), and one O(3) atom. There are four inequivalent O sites. In the first O site, O(1) is bonded in a 2-coordinate geometry to one N(1) and one O(2) atom. In the second O site, O(2) is bonded in a 5-coordinate geometry to four equivalent Rb(3) and one O(1) atom. In the third O site, O(3) is bonded in a distorted single-bond geometry to two equivalent Rb(3) and one N(1) atom. In the fourth O site, O(4) is bonded in a 4-coordinate geometry to one Rb(3) and three equivalent Rb(1) atoms.
