Materials Data on CrF3 by Materials Project
CrF3 is Bismuth triodide-like structured and crystallizes in the monoclinic C2/c space group. The structure is one-dimensional and consists of two CrF3 ribbons oriented in the (0, 0, 1) direction. Cr3+ is bonded to six F1- atoms to form distorted face-sharing CrF6 octahedra. There is four shorter (1.97 Å) and two longer (1.98 Å) Cr–F bond length. There are two inequivalent F1- sites. In the first F1- site, F1- is bonded in an L-shaped geometry to two equivalent Cr3+ atoms. In the second F1- site, F1- is bonded in an L-shaped geometry to two equivalent Cr3+ atoms.
