Li2MnF4 crystallizes in the orthorhombic Pbam space group. Li(1) is bonded in a 6-coordinate geometry to two equivalent F(2) and four 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(2) is bonded to two equivalent Li(1) and two equivalent Mn(1) atoms to form a mixture of distorted edge and corner-sharing FLi2Mn2 trigonal pyramids. In the second F site, F(1) is bonded in a 5-coordinate geometry to four equivalent Li(1) and one Mn(1) atom.
Li2MnF4 crystallizes in the orthorhombic Pbam space group. Li(1) is bonded in a 6-coordinate geometry to two equivalent F(2) and four equivalent F(1) atoms. There is one shorter (1.93 Å) and one longer (2.17 Å) Li(1)-F(2) bond length. There are two shorter (1.98 Å) and two longer (2.41 Å) Li(1)-F(1) bond lengths. 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 2.14 Å. All Mn(1)-F(2) bond lengths are 2.16 Å. There are two inequivalent F sites. In the first F site, F(2) is bonded to two equivalent Li(1) and two equivalent Mn(1) atoms to form a mixture of distorted edge and corner-sharing FLi2Mn2 trigonal pyramids. In the second F site, F(1) is bonded in a 5-coordinate geometry to four equivalent Li(1) and one Mn(1) atom.
