The crystal structure described by Li2Mn3F10 crystallizes in the monoclinic C2/m space group. There are two inequivalent Li sites. In the first Li site, Li(1) is bonded to one F(1), two equivalent F(4), and two equivalent F(8) atoms to form LiF5 square pyramids that share corners with two equivalent Mn(1)F6 octahedra, corners with two equivalent Mn(3)F6 octahedra, edges with two equivalent Mn(1)F6 octahedra, and  an edgeedge with one Li(1)F5 square pyramid. The corner-sharing octahedral tilt angles range from 11-50°. In the second Li site, Li(2) is bonded in a trigonal non-coplanar geometry to one F(6) and two equivalent F(4) atoms. There are three inequivalent Mn sites. In the first Mn site, Mn(1) is bonded to one F(2), one F(3), two equivalent F(4), and two equivalent F(8) atoms to form MnF6 octahedra that share  a cornercorner with one Mn(2)F6 octahedra, corners with two equivalent Mn(3)F6 octahedra, corners with two equivalent Li(1)F5 square pyramids,  an edgeedge with one Mn(1)F6 octahedra, and edges with two equivalent Li(1)F5 square pyramids. The corner-sharing octahedral tilt angles range from 3-48°. In the second Mn site, Mn(2) is bonded to one F(3), one F(6), two equivalent F(5), and two equivalent F(7) atoms to form corner-sharing MnF6 octahedra. The corner-sharing octahedral tilt angles range from 0-41°. In the third Mn site, Mn(3) is bonded to two equivalent F(1), two equivalent F(2), and two equivalent F(5) atoms to form MnF6 octahedra that share corners with two equivalent Mn(1)F6 octahedra, corners with two equivalent Mn(2)F6 octahedra, corners with two equivalent Li(1)F5 square pyramids, and edges with two equivalent Mn(3)F6 octahedra. The corner-sharing octahedral tilt angles range from 41-48°. There are eight inequivalent F sites. In the first F site, F(8) is bonded in a rectangular see-saw-like geometry to two equivalent Li(1) and two equivalent Mn(1) atoms. In the second F site, F(1) is bonded in a distorted trigonal planar geometry to one Li(1) and two equivalent Mn(3) atoms. In the third F site, F(2) is bonded in a distorted trigonal planar geometry to one Mn(1) and two equivalent Mn(3) atoms. In the fourth F site, F(3) is bonded in a linear geometry to one Mn(1) and one Mn(2) atom. In the fifth F site, F(4) is bonded in a T-shaped geometry to one Li(1), one Li(2), and one Mn(1) atom. In the sixth F site, F(5) is bonded in a bent 150 degrees geometry to one Mn(2) and one Mn(3) atom. In the seventh F site, F(6) is bonded in a bent 150 degrees geometry to one Li(2) and one Mn(2) atom. In the eighth F site, F(7) is bonded in a linear geometry to two equivalent Mn(2) atoms. is represented by the CIF card [CIF]
