Materials Data on FeCu(C3N4)2 by Materials Project
FeCu(CN)6N2 is Heusler structured and crystallizes in the cubic Fm-3m space group. The structure is zero-dimensional and consists of eight ammonia molecules, four iron molecules, and four Cu(CN)6 clusters. In each Cu(CN)6 cluster, Cu1+ is bonded in an octahedral geometry to six equivalent N3- atoms. All Cu–N bond lengths are 2.02 Å. C+3.33+ is bonded in a single-bond geometry to one N3- atom. The C–N bond length is 1.17 Å. N3- is bonded in a linear geometry to one Cu1+ and one C+3.33+ atom.
