Materials Data on SbC2N2F5 by Materials Project
CNCSbNF5 crystallizes in the orthorhombic C222_1 space group. The structure is zero-dimensional and consists of four hydrogen cyanide molecules and four CSbNF5 clusters. In each CSbNF5 cluster, C4+ is bonded in a single-bond geometry to one N3- atom. The C–N bond length is 1.16 Å. Sb3+ is bonded in a distorted octahedral geometry to one N3- and five F1- atoms. The Sb–N bond length is 2.26 Å. There is one shorter (1.88 Å) and four longer (1.90 Å) Sb–F bond length. N3- is bonded in a 1-coordinate geometry to one C4+ and one Sb3+ atom. There are three inequivalent F1- sites. In the first F1- site, F1- is bonded in a single-bond geometry to one Sb3+ atom. In the second F1- site, F1- is bonded in a single-bond geometry to one Sb3+ atom. In the third F1- site, F1- is bonded in a single-bond geometry to one Sb3+ atom.
