Li2MnF4 crystallizes in the monoclinic C2/c space group. Li(1) is bonded in a 4-coordinate geometry to two equivalent F(2) and three equivalent F(1) atoms. Mn(1) is bonded to two equivalent F(1) and four equivalent F(2) atoms to form edge-sharing MnF6 octahedra. There are two inequivalent F sites. In the first F site, F(1) is bonded to three equivalent Li(1) and one Mn(1) atom to form a mixture of corner and edge-sharing FLi3Mn trigonal pyramids. In the second F site, F(2) is bonded in a 4-coordinate geometry to two equivalent Li(1) and two equivalent Mn(1) atoms.
Li2MnF4 crystallizes in the monoclinic C2/c space group. Li(1) is bonded in a 4-coordinate geometry to two equivalent F(2) and three equivalent F(1) atoms. There is one shorter (1.92 Å) and one longer (2.51 Å) Li(1)-F(2) bond length. There are a spread of Li(1)-F(1) bond distances ranging from 1.92-2.04 Å. Mn(1) is bonded to two equivalent F(1) and four equivalent F(2) atoms to form edge-sharing MnF6 octahedra. Both Mn(1)-F(1) bond lengths are 2.12 Å. There are two shorter (2.14 Å) and two longer (2.20 Å) Mn(1)-F(2) bond lengths. There are two inequivalent F sites. In the first F site, F(1) is bonded to three equivalent Li(1) and one Mn(1) atom to form a mixture of corner and edge-sharing FLi3Mn trigonal pyramids. In the second F site, F(2) is bonded in a 4-coordinate geometry to two equivalent Li(1) and two equivalent Mn(1) atoms.
