Materials Data on K2FeNi(CN)6 by Materials Project
(K)2FeNi(CN)6 is Heusler structured and crystallizes in the cubic Fm-3m space group. The structure is zero-dimensional and consists of four iron molecules, eight potassium molecules, and four Ni(CN)6 clusters. In each Ni(CN)6 cluster, Ni2+ is bonded in an octahedral geometry to six equivalent N3- atoms. All Ni–N bond lengths are 2.04 Å. C+1.83+ is bonded in a single-bond geometry to one N3- atom. The C–N bond length is 1.18 Å. N3- is bonded in a linear geometry to one Ni2+ and one C+1.83+ atom.
