The compound described by Li2MnF5 crystallizes in the orthorhombic Pnma space group. Li(1) is bonded to one F(1), one F(2), and two equivalent F(4) atoms to form LiF4 trigonal pyramids that share corners with four equivalent Mn(1)F6 octahedra, corners with two equivalent Li(1)F4 trigonal pyramids, and  an edgeedge with one Li(1)F4 trigonal pyramid. The corner-sharing octahedral tilt angles range from 48-67°. Mn(1) is bonded to one F(1), one F(2), two equivalent F(3), and two equivalent F(4) atoms to form distorted MnF6 octahedra that share corners with two equivalent Mn(1)F6 octahedra and corners with eight equivalent Li(1)F4 trigonal pyramids. The corner-sharing octahedral tilt angles are 28°. There are four inequivalent F sites. In the first F site, F(1) is bonded in a distorted trigonal planar geometry to two equivalent Li(1) and one Mn(1) atom. In the second F site, F(2) is bonded in a distorted T-shaped geometry to two equivalent Li(1) and one Mn(1) atom. In the third F site, F(3) is bonded in a bent 150 degrees geometry to two equivalent Mn(1) atoms. In the fourth F site, F(4) is bonded in a trigonal non-coplanar geometry to two equivalent Li(1) and one Mn(1) atom. is represented by the CIF card [CIF]
