The structure described by Li2Mn2F7 crystallizes in the orthorhombic P2_12_12_1 space group. There are two inequivalent Li sites. In the first Li site, Li(1) is bonded in a 4-coordinate geometry to one F(2), one F(3), one F(4), one F(5), and one F(6) atom. In the second Li site, Li(2) is bonded in a 5-coordinate geometry to one F(1), one F(2), one F(4), one F(5), and one F(6) atom. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded to one F(1), one F(2), one F(3), one F(6), and one F(7) atom to form a mixture of edge and corner-sharing MnF5 square pyramids. In the second Mn site, Mn(2) is bonded to one F(1), one F(3), one F(4), one F(5), and one F(7) atom to form a mixture of edge and corner-sharing MnF5 trigonal bipyramids. There are seven inequivalent F sites. In the first F site, F(1) is bonded in a distorted T-shaped geometry to one Li(2), one Mn(1), and one Mn(2) atom. In the second F site, F(2) is bonded in a distorted T-shaped geometry to one Li(1), one Li(2), and one Mn(1) atom. In the third F site, F(3) is bonded in a 3-coordinate geometry to one Li(1), one Mn(1), and one Mn(2) atom. In the fourth F site, F(4) is bonded in a distorted T-shaped geometry to one Li(1), one Li(2), and one Mn(2) atom. In the fifth F site, F(5) is bonded in a distorted trigonal planar geometry to one Li(1), one Li(2), and one Mn(2) atom. In the sixth F site, F(6) is bonded in a 3-coordinate geometry to one Li(1), one Li(2), and one Mn(1) atom. In the seventh F site, F(7) is bonded in a bent 150 degrees geometry to one Mn(1) and one Mn(2) atom. is represented by the CIF card [CIF]
