Abstract

Zn(CoZn(CN)6)2 is High-temperature superconductor-derived structured and crystallizes in the tetragonal P-4m2 space group. The structure is three-dimensional and consists of one CoZn(CN)6 framework and one zinc molecule. In the CoZn(CN)6 framework, there are two inequivalent Co2+ sites. In the first Co2+ site, Co2+ is bonded in an octahedral geometry to six C+2.17+ atoms. All Co–C bond lengths are 1.87 Å. In the second Co2+ site, Co2+ is bonded in an octahedral geometry to six C+2.17+ atoms. All Co–C bond lengths are 1.87 Å. Zn2+ is bonded in an octahedral geometry to six N3- atoms. There are a spread of Zn–N bond distances ranging from 2.08–2.17 Å. There are three inequivalent C+2.17+ sites. In the first C+2.17+ site, C+2.17+ is bonded in a linear geometry to one Co2+ and 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 linear geometry to one Co2+ and 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 linear geometry to one Co2+ and one N3- atom. The C–N bond length is 1.17 Å. There are three inequivalent N3- sites. In the first N3- site, N3- is bonded in a linear geometry to one Zn2+ and one C+2.17+ atom. In the second N3- site, N3- is bonded in a linear geometry to one Zn2+ and one C+2.17+ atom. In the third N3- site, N3- is bonded in a linear geometry to one Zn2+ and one C+2.17+ atom.
