The material structure described by Li2MnF4 crystallizes in the orthorhombic Cmcm space group. Li(1) is bonded to one F(2), two equivalent F(1), and three equivalent F(3) atoms to form a mixture of corner and edge-sharing LiF6 octahedra. The corner-sharing octahedral tilt angles range from 0-47°. Mn(1) is bonded in a 6-coordinate geometry to two equivalent F(2) and four equivalent F(3) atoms. There are three inequivalent F sites. In the first F site, F(1) is bonded in a square co-planar geometry to four equivalent Li(1) atoms. In the second F site, F(2) is bonded to two equivalent Li(1) and two equivalent Mn(1) atoms to form distorted FLi2Mn2 tetrahedra that share corners with two equivalent F(2)Li2Mn2 tetrahedra, corners with ten equivalent F(3)Li3Mn2 trigonal bipyramids, and edges with two equivalent F(3)Li3Mn2 trigonal bipyramids. In the third F site, F(3) is bonded to three equivalent Li(1) and two equivalent Mn(1) atoms to form distorted FLi3Mn2 trigonal bipyramids that share corners with five equivalent F(2)Li2Mn2 tetrahedra, corners with two equivalent F(3)Li3Mn2 trigonal bipyramids,  an edgeedge with one F(2)Li2Mn2 tetrahedra, and edges with five equivalent F(3)Li3Mn2 trigonal bipyramids. is represented by the CIF card [CIF]
