The crystal structure described by V2F7 crystallizes in the monoclinic P2_1 space group. There are four inequivalent V sites. In the first V site, V(1) is bonded to one F(13), one F(2), one F(6), one F(8), and two equivalent F(3) atoms to form corner-sharing VF6 octahedra. The corner-sharing octahedral tilt angles range from 33-42°. In the second V site, V(2) is bonded to one F(10), one F(11), one F(4), one F(7), and two equivalent F(1) atoms to form a mixture of distorted corner and edge-sharing VF6 octahedra. The corner-sharing octahedral tilt angles range from 32-51°. In the third V site, V(3) is bonded to one F(12), one F(13), one F(14), one F(5), one F(8), and one F(9) atom to form corner-sharing VF6 octahedra. The corner-sharing octahedral tilt angles range from 36-44°. In the fourth V site, V(4) is bonded to one F(10), one F(14), one F(7), one F(9), and two equivalent F(11) atoms to form a mixture of corner and edge-sharing VF6 octahedra. The corner-sharing octahedral tilt angles range from 32-51°. There are fourteen inequivalent F sites. In the first F site, F(1) is bonded in a bent 150 degrees geometry to two equivalent V(2) atoms. In the second F site, F(2) is bonded in a single-bond geometry to one V(1) atom. In the third F site, F(3) is bonded in a bent 150 degrees geometry to two equivalent V(1) atoms.
