Materials Data on K2Fe2Co2C12N12O by Materials Project
K2O(Fe)2(Co(CN)6)2 crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of two iron molecules, one potassium monoxide molecule, and two Co(CN)6 clusters. In each Co(CN)6 cluster, Co2+ is bonded in an octahedral geometry to six N3- atoms. There are a spread of Co–N bond distances ranging from 2.09–2.15 Å. There are six inequivalent C+2.17+ sites. In the first C+2.17+ site, C+2.17+ is bonded in a single-bond geometry to one N3- atom. The C–N bond length is 1.17 Å. In the second C+2.17+ site, C+2.17+ is bonded in a single-bond geometry to one N3- atom. The C–N bond length is 1.17 Å. In the third C+2.17+ site, C+2.17+ is bonded in a single-bond geometry to one N3- atom. The C–N bond length is 1.17 Å. In the fourth C+2.17+ site, C+2.17+ is bonded in a single-bond geometry to one N3- atom. The C–N bond length is 1.17 Å. In the fifth C+2.17+ site, C+2.17+ is bonded in a single-bond geometry to one N3- atom. The C–N bond length is 1.17 Å. In the sixth C+2.17+ site, C+2.17+ is bonded in a single-bond geometry to one N3- atom. The C–N bond length is 1.17 Å. There are six inequivalent N3- sites. In the first N3- site, N3- is bonded in a distorted linear geometry to one Co2+ and one C+2.17+ atom. In the second N3- site, N3- is bonded in a linear geometry to one Co2+ and one C+2.17+ atom. In the third N3- site, N3- is bonded in a linear geometry to one Co2+ and one C+2.17+ atom. In the fourth N3- site, N3- is bonded in a linear geometry to one Co2+ and one C+2.17+ atom. In the fifth N3- site, N3- is bonded in a linear geometry to one Co2+ and one C+2.17+ atom. In the sixth N3- site, N3- is bonded in a linear geometry to one Co2+ and one C+2.17+ atom.
