The structure described by LiMn2F7 crystallizes in the monoclinic P2_1/c space group. Li(1) is bonded to one F(2), one F(6), one F(7), and two equivalent F(5) atoms to form distorted LiF5 square pyramids that share corners with three equivalent Mn(1)F6 octahedra and  an edgeedge with one Li(1)F5 square pyramid. The corner-sharing octahedral tilt angles range from 47-54°. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded to one F(2), one F(3), one F(4), one F(5), and two equivalent F(1) atoms to form MnF6 octahedra that share corners with three equivalent Li(1)F5 square pyramids and  an edgeedge with one Mn(1)F6 octahedra. In the second Mn site, Mn(2) is bonded in a 6-coordinate geometry to one F(3), one F(4), one F(5), one F(7), and two equivalent F(6) atoms. There are seven inequivalent F sites. In the first F site, F(1) is bonded in a water-like geometry to two equivalent Mn(1) atoms. In the second F site, F(2) is bonded in a bent 120 degrees geometry to one Li(1) and one Mn(1) atom. In the third F site, F(3) is bonded in a water-like geometry to one Mn(1) and one Mn(2) atom. In the fourth F site, F(4) is bonded in a bent 150 degrees geometry to one Mn(1) and one Mn(2) atom. In the fifth F site, F(5) is bonded to two equivalent Li(1), one Mn(1), and one Mn(2) atom to form distorted edge-sharing FLi2Mn2 trigonal pyramids. In the sixth F site, F(6) is bonded in a distorted trigonal planar geometry to one Li(1) and two equivalent Mn(2) atoms. In the seventh F site, F(7) is bonded in a bent 150 degrees geometry to one Li(1) and one Mn(2) atom. is represented by the CIF card [CIF]
