The compound described by KCN crystallizes in the monoclinic Cc space group. K(1) is bonded to four equivalent C(1) and four equivalent N(1) atoms to form distorted edge-sharing KC4N4 hexagonal bipyramids. C(1) is bonded in a distorted single-bond geometry to four equivalent K(1) and one N(1) atom. N(1) is bonded in a distorted single-bond geometry to four equivalent K(1) and one C(1) atom. is represented by the CIF card [CIF]
