Materials Data on FeCu2(CN)6 by Materials Project

Cu2Fe(CN)6 is alpha Rhenium trioxide-derived structured and crystallizes in the cubic F-43m space group. The structure is three-dimensional and consists of four cuprum molecules and one FeCu(CN)6 framework. In the FeCu(CN)6 framework, Fe2+ is bonded in an octahedral geometry to six equivalent C+2.33+ atoms. All Fe–C bond lengths are 1.88 Å. Cu1+ is bonded in an octahedral geometry to six equivalent N3- atoms. All Cu–N bond lengths are 2.04 Å. C+2.33+ is bonded in a linear geometry to one Fe2+ and 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+2.33+ atom.
