The structure described by Li2MnF5 crystallizes in the orthorhombic Pnma space group. There are two inequivalent Li sites. In the first Li site, Li(1) is bonded in a distorted rectangular see-saw-like geometry to two equivalent F(3) and two equivalent F(4) atoms. In the second Li site, Li(2) is bonded to one F(2) and four equivalent F(3) atoms to form distorted LiF5 trigonal bipyramids that share corners with three equivalent Mn(1)F6 octahedra,  an edgeedge with one Mn(1)F6 octahedra, and edges with two equivalent Li(2)F5 trigonal bipyramids. The corner-sharing octahedral tilt angles range from 7-62°. Mn(1) is bonded to one F(2), one F(4), two equivalent F(1), and two equivalent F(3) atoms to form MnF6 octahedra that share corners with two equivalent Mn(1)F6 octahedra, corners with three equivalent Li(2)F5 trigonal bipyramids, and  an edgeedge with one Li(2)F5 trigonal bipyramid. The corner-sharing octahedra are not tilted. There are four inequivalent F sites. In the first F site, F(1) is bonded in a linear geometry to two equivalent Mn(1) atoms. In the second F site, F(2) is bonded in a linear geometry to one Li(2) and one Mn(1) atom. In the third F site, F(3) is bonded to one Li(1), two equivalent Li(2), and one Mn(1) atom to form a mixture of distorted corner and edge-sharing FLi3Mn trigonal pyramids. In the fourth F site, F(4) is bonded in a distorted trigonal planar geometry to two equivalent Li(1) and one Mn(1) atom. is represented by the CIF card [CIF]
