The material structure described by K5(CN2)3 crystallizes in the cubic Im-3m space group. There are two inequivalent K sites. In the first K site, K(1) is bonded to six equivalent N(1) atoms to form face-sharing KN6 octahedra. In the second K site, K(2) is bonded to six equivalent N(1) atoms to form a mixture of face, edge, and corner-sharing KN6 octahedra. The corner-sharing octahedral tilt angles are 30°. C(1) is bonded in a linear geometry to two equivalent N(1) atoms. N(1) is bonded in a 6-coordinate geometry to one K(1), four equivalent K(2), and one C(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
