Materials Data on Tl4Fe(CN)6 by Materials Project
Fe(Tl2(CN)3)2 crystallizes in the triclinic P-1 space group. The structure is three-dimensional and consists of two iron molecules and one Tl2(CN)3 framework. In the Tl2(CN)3 framework, there are four inequivalent Tl1+ sites. In the first Tl1+ site, Tl1+ is bonded in a 2-coordinate geometry to five N3- atoms. There are a spread of Tl–N bond distances ranging from 2.84–3.50 Å. In the second Tl1+ site, Tl1+ is bonded to six N3- atoms to form distorted edge-sharing TlN6 octahedra. There are a spread of Tl–N bond distances ranging from 2.91–3.18 Å. In the third Tl1+ site, Tl1+ is bonded to six N3- atoms to form distorted edge-sharing TlN6 octahedra. There are a spread of Tl–N bond distances ranging from 2.92–3.32 Å. In the fourth Tl1+ site, Tl1+ is bonded in a 6-coordinate geometry to six N3- atoms. There are a spread of Tl–N bond distances ranging from 2.83–3.61 Å. There are six inequivalent C+1.83+ sites. In the first C+1.83+ site, C+1.83+ is bonded in a single-bond geometry to one N3- atom. The C–N bond length is 1.19 Å. In the second C+1.83+ site, C+1.83+ is bonded in a single-bond geometry to one N3- atom. The C–N bond length is 1.19 Å. In the third C+1.83+ site, C+1.83+ is bonded in a single-bond geometry to one N3- atom. The C–N bond length is 1.19 Å. In the fourth C+1.83+ site, C+1.83+ is bonded in a single-bond geometry to one N3- atom. The C–N bond length is 1.19 Å. In the fifth C+1.83+ site, C+1.83+ is bonded in a single-bond geometry to one N3- atom. The C–N bond length is 1.19 Å. In the sixth C+1.83+ site, C+1.83+ is bonded in a distorted single-bond geometry to one N3- atom. The C–N bond length is 1.19 Å. There are six inequivalent N3- sites. In the first N3- site, N3- is bonded in a distorted single-bond geometry to four Tl1+ and one C+1.83+ atom. In the second N3- site, N3- is bonded in a single-bond geometry to four Tl1+ and one C+1.83+ atom. In the third N3- site, N3- is bonded in a distorted single-bond geometry to four Tl1+ and one C+1.83+ atom. In the fourth N3- site, N3- is bonded in a distorted single-bond geometry to four Tl1+ and one C+1.83+ atom. In the fifth N3- site, N3- is bonded in a distorted single-bond geometry to four Tl1+ and one C+1.83+ atom. In the sixth N3- site, N3- is bonded in a distorted single-bond geometry to three Tl1+ and one C+1.83+ atom.
