Abstract

LiFe2F5 crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are four inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to four F1- atoms to form LiF4 tetrahedra that share corners with four FeF6 octahedra. The corner-sharing octahedra tilt angles range from 58–59°. There are a spread of Li–F bond distances ranging from 1.82–1.92 Å. In the second Li1+ site, Li1+ is bonded to four F1- atoms to form LiF4 tetrahedra that share corners with four FeF6 octahedra and corners with two equivalent FeF5 trigonal bipyramids. The corner-sharing octahedra tilt angles range from 58–59°. There are a spread of Li–F bond distances ranging from 1.82–1.91 Å. In the third Li1+ site, Li1+ is bonded to four F1- atoms to form LiF4 tetrahedra that share corners with four FeF6 octahedra and a cornercorner with one FeF5 trigonal bipyramid.
