Li2Cu2F5 crystallizes in the triclinic P-1 space group. There are two inequivalent Li sites. In the first Li site, Li(1) is bonded to one F(3), one F(5), two equivalent F(1), and two equivalent F(4) atoms to form edge-sharing LiF6 octahedra. In the second Li site, Li(2) is bonded to one F(1), two equivalent F(3), and three equivalent F(2) atoms to form edge-sharing LiF6 octahedra. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded in a T-shaped geometry to one F(1), one F(2), and one F(5) atom. In the second Cu site, Cu(2) is bonded in a distorted T-shaped geometry to one F(3), one F(4), and one F(5) atom. There are five inequivalent F sites. In the first F site, F(1) is bonded to one Li(2), two equivalent Li(1), and one Cu(1) atom to form corner-sharing FLi3Cu trigonal pyramids. In the second F site, F(2) is bonded in a rectangular see-saw-like geometry to three equivalent Li(2) and one Cu(1) atom. In the third F site, F(3) is bonded in a rectangular see-saw-like geometry to one Li(1), two equivalent Li(2), and one Cu(2) atom. In the fourth F site, F(4) is bonded in a distorted trigonal planar geometry to two equivalent Li(1) and one Cu(2) atom. In the fifth F site, F(5) is bonded in a distorted T-shaped geometry to one Li(1), one Cu(1), and one Cu(2) atom.
