Materials Data on AsC18F17 by Materials Project
C3AsF2(CF)15 crystallizes in the orthorhombic Pbcn space group. The structure is zero-dimensional and consists of sixty fluoromethane molecules and four C3AsF2 clusters. In each C3AsF2 cluster, there are two inequivalent C+1.11+ sites. In the first C+1.11+ site, C+1.11+ is bonded in a single-bond geometry to one As3- atom. The C–As bond length is 1.94 Å. In the second C+1.11+ site, C+1.11+ is bonded in a single-bond geometry to one As3- atom. The C–As bond length is 1.93 Å. As3- is bonded in a trigonal bipyramidal geometry to three C+1.11+ and two equivalent F1- atoms. Both As–F bond lengths are 1.83 Å. F1- is bonded in a single-bond geometry to one As3- atom.
