Materials Data on CoAu2(CN)4 by Materials Project
CoAu2(CN)4 crystallizes in the hexagonal P6_422 space group. The structure is three-dimensional and consists of two CoAu2(CN)4 frameworks. Co2+ is bonded in a tetrahedral geometry to four N3- atoms. All Co–N bond lengths are 1.93 Å. Au1+ is bonded in a distorted linear geometry to two C2+ atoms. Both Au–C bond lengths are 1.99 Å. There are two inequivalent C2+ sites. In the first C2+ site, C2+ is bonded in a distorted single-bond geometry to one Au1+ and one N3- atom. The C–N bond length is 1.17 Å. In the second C2+ site, C2+ is bonded in a distorted single-bond geometry to one Au1+ and one N3- atom. The C–N bond length is 1.17 Å. There are two inequivalent N3- sites. In the first N3- site, N3- is bonded in a linear geometry to one Co2+ and one C2+ atom. In the second N3- site, N3- is bonded in a linear geometry to one Co2+ and one C2+ atom.
