Materials Data on Tl2Ni(CN)4 by Materials Project
Ni(Tl(CN)2)2 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional and consists of two nickel molecules and one Tl(CN)2 framework. In the Tl(CN)2 framework, Tl1+ is bonded in a 5-coordinate geometry to five N3- atoms. There are a spread of Tl–N bond distances ranging from 2.83–3.11 Å. There are two inequivalent C2+ sites. In the first C2+ site, C2+ is bonded in a single-bond geometry to one N3- atom. The C–N bond length is 1.18 Å. In the second C2+ site, C2+ is bonded in a single-bond geometry to one N3- atom. The C–N bond length is 1.18 Å. There are two inequivalent N3- sites. In the first N3- site, N3- is bonded in a distorted single-bond geometry to two equivalent Tl1+ and one C2+ atom. In the second N3- site, N3- is bonded in a distorted single-bond geometry to three equivalent Tl1+ and one C2+ atom.
