Materials Data on AsCClO2F3 by Materials Project

CF3AsO2Cl crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of four fluoroform molecules and two AsO2Cl clusters. In each AsO2Cl cluster, As5+ is bonded in a distorted see-saw-like geometry to three O2- and one Cl1- atom. There are a spread of As–O bond distances ranging from 1.73–1.90 Å. The As–Cl bond length is 2.31 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a single-bond geometry to one As5+ atom. In the second O2- site, O2- is bonded in a distorted L-shaped geometry to two equivalent As5+ atoms. Cl1- is bonded in a 1-coordinate geometry to one As5+ atom.
