NaC2PH6(NO)4 crystallizes in the monoclinic C2/c space group. Na(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form NaO6 octahedra that share corners with two equivalent P(1)N2O2 tetrahedra and edges with two equivalent Na(1)O6 octahedra. C(1) is bonded in a trigonal planar geometry to one N(1), one N(2), and one O(2) atom. P(1) is bonded to two equivalent N(1) and two equivalent O(1) atoms to form PN2O2 tetrahedra that share corners with two equivalent Na(1)O6 octahedra. The corner-sharing octahedral tilt angles are 50°. 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 P(1), and one H(1) atom. In the second N site, N(2) is bonded in a trigonal planar geometry to one C(1), one H(2), 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(2) 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 distorted bent 120 degrees geometry to one Na(1) and one P(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to two equivalent Na(1) and one C(1) atom.
