Li2Cu2F5 crystallizes in the monoclinic C2/c space group. Li(1) is bonded to one F(1), one F(2), one F(3), and one F(4) atom to form distorted LiF4 tetrahedra that share corners with three equivalent Li(1)F4 tetrahedra, corners with four equivalent Cu(1)F5 trigonal bipyramids, and edges with two equivalent Cu(1)F5 trigonal bipyramids. Cu(1) is bonded to one F(1), one F(3), one F(4), and two equivalent F(2) atoms to form distorted CuF5 trigonal bipyramids that share corners with four equivalent Li(1)F4 tetrahedra, corners with five equivalent Cu(1)F5 trigonal bipyramids, and edges with two equivalent Li(1)F4 tetrahedra. There are four inequivalent F sites. In the first F site, F(1) is bonded in a square co-planar geometry to two equivalent Li(1) and two equivalent Cu(1) atoms. In the second F site, F(2) is bonded in a distorted trigonal planar geometry to one Li(1) and two equivalent Cu(1) atoms. In the third F site, F(3) is bonded in a distorted tetrahedral geometry to two equivalent Li(1) and two equivalent Cu(1) atoms. In the fourth F site, F(4) is bonded in a square co-planar geometry to two equivalent Li(1) and two equivalent Cu(1) atoms.
