The material structure described by Li2VF7 crystallizes in the orthorhombic Pnma space group. There are two inequivalent Li sites. In the first Li site, Li(1) is bonded to one F(1), two equivalent F(3), two equivalent F(4), and two equivalent F(5) atoms to form distorted LiF7 pentagonal bipyramids that share corners with three equivalent V(1)F6 octahedra, corners with two equivalent Li(1)F7 pentagonal bipyramids, and  an edgeedge with one V(1)F6 octahedra. The corner-sharing octahedral tilt angles range from 28-52°. In the second Li site, Li(2) is bonded in a 5-coordinate geometry to one F(1), one F(2), one F(3), and two equivalent F(5) atoms. V(1) is bonded to one F(1), one F(2), two equivalent F(4), and two equivalent F(5) atoms to form VF6 octahedra that share corners with three equivalent Li(1)F7 pentagonal bipyramids and  an edgeedge with one Li(1)F7 pentagonal bipyramid. There are five inequivalent F sites. In the first F site, F(1) is bonded in a distorted bent 150 degrees geometry to one Li(1), one Li(2), and one V(1) atom. In the second F site, F(2) is bonded in a bent 120 degrees geometry to one Li(2) and one V(1) atom. In the third F site, F(3) is bonded in a trigonal planar geometry to one Li(2) and two equivalent Li(1) atoms. In the fourth F site, F(4) is bonded in a bent 150 degrees geometry to one Li(1) and one V(1) 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 V(1) atom. is represented by the CIF card [CIF]
