Rb2UF6 crystallizes in the orthorhombic Cmcm space group. Rb(1) is bonded in a 9-coordinate geometry to one F(1), four equivalent F(2), and four equivalent F(3) atoms. U(1) is bonded in a 8-coordinate geometry to two equivalent F(2), two equivalent F(3), and four equivalent F(1) atoms. There are three inequivalent F sites. In the first F site, F(1) is bonded in a 3-coordinate geometry to one Rb(1) and two equivalent U(1) atoms. In the second F site, F(2) is bonded in a 5-coordinate geometry to four equivalent Rb(1) and one U(1) atom. In the third F site, F(3) is bonded in a 5-coordinate geometry to four equivalent Rb(1) and one U(1) atom.
Rb2UF6 crystallizes in the orthorhombic Cmcm space group. Rb(1) is bonded in a 9-coordinate geometry to one F(1), four equivalent F(2), and four equivalent F(3) atoms. The Rb(1)-F(1) bond length is 2.95 Å. All Rb(1)-F(2) bond lengths are 2.88 Å. There are two shorter (2.95 Å) and two longer (3.09 Å) Rb(1)-F(3) bond lengths. U(1) is bonded in a 8-coordinate geometry to two equivalent F(2), two equivalent F(3), and four equivalent F(1) atoms. Both U(1)-F(2) bond lengths are 2.27 Å. Both U(1)-F(3) bond lengths are 2.19 Å. There are two shorter (2.28 Å) and two longer (2.43 Å) U(1)-F(1) bond lengths. There are three inequivalent F sites.
