The crystal structure described by U2AuF11 crystallizes in the tetragonal I4/mcm space group. U(1) is bonded in a 9-coordinate geometry to one F(3), two equivalent F(2), two equivalent F(4), and four equivalent F(1) atoms. Au(1) is bonded in a square co-planar geometry to four equivalent F(2) atoms. There are four inequivalent F sites. In the first F site, F(1) is bonded in a bent 150 degrees geometry to two equivalent U(1) atoms. In the second F site, F(2) is bonded in a linear geometry to one U(1) and one Au(1) atom. In the third F site, F(3) is bonded in a linear geometry to two equivalent U(1) atoms. In the fourth F site, F(4) is bonded in a linear geometry to two equivalent U(1) atoms. is represented by the CIF file [CIF]
