Sr2CuF6 crystallizes in the orthorhombic Cmce space group. Sr(1) is bonded in a body-centered cubic geometry to four equivalent F(1) and four equivalent F(2) atoms. Cu(1) is bonded in a square co-planar geometry to four equivalent F(1) atoms. There are two inequivalent F sites. In the first F site, F(1) is bonded in a distorted trigonal planar geometry to two equivalent Sr(1) and one Cu(1) atom. In the second F site, F(2) is bonded to four equivalent Sr(1) atoms to form a mixture of edge and corner-sharing FSr4 tetrahedra.
Sr2CuF6 crystallizes in the orthorhombic Cmce space group. Sr(1) is bonded in a body-centered cubic geometry to four equivalent F(1) and four equivalent F(2) atoms. All Sr(1)-F(1) bond lengths are 2.51 Å. There are two shorter (2.47 Å) and two longer (2.51 Å) Sr(1)-F(2) bond lengths. Cu(1) is bonded in a square co-planar geometry to four equivalent F(1) atoms. All Cu(1)-F(1) bond lengths are 1.89 Å. There are two inequivalent F sites. In the first F site, F(1) is bonded in a distorted trigonal planar geometry to two equivalent Sr(1) and one Cu(1) atom. In the second F site, F(2) is bonded to four equivalent Sr(1) atoms to form a mixture of edge and corner-sharing FSr4 tetrahedra.
