Materials Data on Tc3C4NCl6 by Materials Project
(TcCl2)3C4N crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of four C4N clusters and four TcCl2 clusters. In each C4N cluster, there are four inequivalent C4+ sites. In the first C4+ site, C4+ is bonded in a single-bond geometry to one N3- atom. The C–N bond length is 1.56 Å. In the second C4+ site, C4+ is bonded in a single-bond geometry to one N3- atom. The C–N bond length is 1.68 Å. In the third C4+ site, C4+ is bonded in a single-bond geometry to one N3- atom. The C–N bond length is 1.43 Å. In the fourth C4+ site, C4+ is bonded in a single-bond geometry to one N3- atom. The C–N bond length is 1.58 Å. N3- is bonded in a 4-coordinate geometry to four C4+ atoms. In each TcCl2 cluster, there are three inequivalent Tc+2.33- sites. In the first Tc+2.33- site, Tc+2.33- is bonded in a distorted T-shaped geometry to three Cl1- atoms. There are a spread of Tc–Cl bond distances ranging from 2.30–2.37 Å. In the second Tc+2.33- site, Tc+2.33- is bonded in a distorted T-shaped geometry to three Cl1- atoms. There are two shorter (2.37 Å) and one longer (2.38 Å) Tc–Cl bond lengths. In the third Tc+2.33- site, Tc+2.33- is bonded in a distorted T-shaped geometry to three Cl1- atoms. There are a spread of Tc–Cl bond distances ranging from 2.31–2.37 Å. There are six inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a 2-coordinate geometry to two Tc+2.33- atoms. In the second Cl1- site, Cl1- is bonded in a 2-coordinate geometry to two Tc+2.33- atoms. In the third Cl1- site, Cl1- is bonded in a 2-coordinate geometry to two Tc+2.33- atoms. In the fourth Cl1- site, Cl1- is bonded in a distorted single-bond geometry to one Tc+2.33- atom. In the fifth Cl1- site, Cl1- is bonded in a single-bond geometry to one Tc+2.33- atom. In the sixth Cl1- site, Cl1- is bonded in a single-bond geometry to one Tc+2.33- atom.
