Materials Data on AsCF3 by Materials Project
CAsF3 crystallizes in the tetragonal P4_2/nmc space group. The structure is zero-dimensional and consists of eight (trifluoromethyl)arsine molecules. C4+ is bonded in a distorted trigonal non-coplanar geometry to one As1- and three F1- atoms. The C–As bond length is 2.05 Å. All C–F bond lengths are 1.37 Å. As1- is bonded in a distorted single-bond geometry to one C4+ atom. There are two inequivalent F1- sites. In the first F1- site, F1- is bonded in a single-bond geometry to one C4+ atom. In the second F1- site, F1- is bonded in a single-bond geometry to one C4+ atom.
