Abstract

Li2CuF4 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Li1+ is bonded in a 6-coordinate geometry to six F1- atoms. There are a spread of Li–F bond distances ranging from 1.95–2.68 Å. Cu2+ is bonded to six F1- atoms to form distorted edge-sharing CuF6 octahedra. There are a spread of Cu–F bond distances ranging from 1.91–2.46 Å. There are two inequivalent F1- sites. In the first F1- site, F1- is bonded in a 5-coordinate geometry to three equivalent Li1+ and two equivalent Cu2+ atoms. In the second F1- site, F1- is bonded to three equivalent Li1+ and one Cu2+ atom to form corner-sharing FLi3Cu tetrahedra.
