The structure described by LiFe2OF3 is Spinel-derived structured and crystallizes in the orthorhombic Pnma space group. Li(1) is bonded in a rectangular see-saw-like geometry to one O(1), one F(1), and two equivalent F(2) atoms. There are two inequivalent Fe sites. In the first Fe site, Fe(1) is bonded to two equivalent O(1), two equivalent F(1), and two equivalent F(2) atoms to form FeO2F4 octahedra that share corners with four equivalent Fe(2)OF5 octahedra, edges with two equivalent Fe(1)O2F4 octahedra, and edges with two equivalent Fe(2)OF5 octahedra. The corner-sharing octahedral tilt angles range from 51-55°. In the second Fe site, Fe(2) is bonded to one O(1), one F(1), and four equivalent F(2) atoms to form FeOF5 octahedra that share corners with four equivalent Fe(1)O2F4 octahedra, corners with four equivalent Fe(2)OF5 octahedra, and edges with two equivalent Fe(1)O2F4 octahedra. The corner-sharing octahedral tilt angles range from 47-55°. O(1) is bonded to one Li(1), one Fe(2), and two equivalent Fe(1) atoms to form corner-sharing OLiFe3 tetrahedra. There are two inequivalent F sites. In the first F site, F(1) is bonded in a rectangular see-saw-like geometry to one Li(1), one Fe(2), and two equivalent Fe(1) atoms. In the second F site, F(2) is bonded in a rectangular see-saw-like geometry to one Li(1), one Fe(1), and two equivalent Fe(2) atoms. is represented by the CIF card [CIF]
