The crystal structure described by NaNO2 crystallizes in the triclinic P-1 space group. Na(1) is bonded in a 7-coordinate geometry to one N(1), three equivalent O(1), and three equivalent O(2) atoms. N(1) is bonded in a trigonal planar geometry to one Na(1), one O(1), and one O(2) atom. There are two inequivalent O sites. In the first O site, O(1) is bonded to three equivalent Na(1) and one N(1) atom to form a mixture of edge and corner-sharing ONa3N tetrahedra. In the second O site, O(2) is bonded in a 4-coordinate geometry to three equivalent Na(1) and one N(1) atom. is represented by the CIF card [CIF]
