Materials Data on CuF2 by Materials Project
CuF2 is zeta iron carbide-like structured and crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Cu2+ is bonded to six equivalent F1- atoms to form a mixture of corner and edge-sharing CuF6 octahedra. The corner-sharing octahedra tilt angles range from 50–52°. There are a spread of Cu–F bond distances ranging from 1.95–2.27 Å. F1- is bonded in a distorted trigonal planar geometry to three equivalent Cu2+ atoms.
