The structure described by NaCN crystallizes in the orthorhombic Imm2 space group. Na(1) is bonded to four equivalent C(1) and four equivalent N(1) atoms to form distorted edge-sharing NaC4N4 hexagonal bipyramids. C(1) is bonded in a distorted single-bond geometry to four equivalent Na(1) and one N(1) atom. N(1) is bonded in a 3-coordinate geometry to four equivalent Na(1) and one C(1) atom. is represented by the CIF file [CIF]
