Materials Data on Rb2NaCo(CN)6 by Materials Project

Abstract

Rb2Na(CN)6Co crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional and consists of two cobalt molecules and one Rb2Na(CN)6 framework. In the Rb2Na(CN)6 framework, Rb1+ is bonded in a 7-coordinate geometry to seven N3- atoms. There are a spread of Rb–N bond distances ranging from 3.07–3.66 Å. Na1+ is bonded in an octahedral geometry to six N3- atoms. There are a spread of Na–N bond distances ranging from 2.53–2.57 Å. There are three inequivalent C+2.33+ sites. In the first C+2.33+ site, C+2.33+ is bonded in a single-bond geometry to one N3- atom. The C–N bond length is 1.18 Å. In the second C+2.33+ site, C+2.33+ is bonded in a single-bond geometry to one N3- atom. The C–N bond length is 1.18 Å. In the third C+2.33+ site, C+2.33+ is bonded in a single-bond geometry to one N3- atom. The C–N bond length is 1.18 Å. There are three inequivalent N3- sites. In the first N3- site, N3- is bonded in a 2-coordinate geometry to two equivalent Rb1+, one Na1+, and one C+2.33+ atom. In the second N3- site, N3- is bonded in a 1-coordinate geometry to two equivalent Rb1+, one Na1+, and one C+2.33+ atom. In the third N3- site, N3- is bonded in a 2-coordinate geometry to three equivalent Rb1+, one Na1+, and one C+2.33+ atom.
