RbC2PH6(NO)4 crystallizes in the orthorhombic Fdd2 space group. Rb(1) is bonded in a distorted body-centered cubic geometry to four equivalent O(1) and four equivalent O(2) atoms. C(1) is bonded in a trigonal planar geometry to one N(1), one N(2), and one O(1) atom. P(1) is bonded in a tetrahedral geometry to two equivalent N(2) and two equivalent O(2) atoms. There are two inequivalent N sites. In the first N site, N(1) is bonded in a trigonal planar geometry to one C(1), one H(1), and one H(2) atom. In the second N site, N(2) is bonded in a trigonal planar geometry to one C(1), one P(1), and one H(3) atom. There are three inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one N(1) atom. In the second H site, H(2) is bonded in a single-bond geometry to one N(1) atom. In the third H site, H(3) is bonded in a single-bond geometry to one N(2) atom. There are two inequivalent O sites. In the first O site, O(1) is bonded in a single-bond geometry to two equivalent Rb(1) and one C(1) atom. In the second O site, O(2) is bonded in a single-bond geometry to two equivalent Rb(1) and one P(1) atom.
