The crystal structure described by NaCNO2 crystallizes in the monoclinic P2_1/c space group. Na(1) is bonded to two equivalent N(1), one O(1), and two equivalent O(2) atoms to form distorted corner-sharing NaN2O3 trigonal bipyramids. C(1) is bonded in a 3-coordinate geometry to one N(1), one O(1), and one O(2) atom. N(1) is bonded in a 4-coordinate geometry to two equivalent Na(1), one C(1), and one O(1) atom. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to one Na(1), one C(1), and one N(1) atom. In the second O site, O(2) is bonded in a trigonal planar geometry to two equivalent Na(1) and one C(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
