RbVCuF6 crystallizes in the orthorhombic Pnma space group. Rb(1) is bonded in a 10-coordinate geometry to one F(2), one F(4), four equivalent F(1), and four equivalent F(3) atoms. V(1) is bonded to two equivalent F(1), two equivalent F(2), and two equivalent F(3) atoms to form VF6 octahedra that share corners with two equivalent V(1)F6 octahedra and corners with four equivalent Cu(1)F6 octahedra. The corner-sharing octahedral tilt angles range from 30-63°. Cu(1) is bonded to two equivalent F(1), two equivalent F(3), and two equivalent F(4) atoms to form CuF6 octahedra that share corners with two equivalent Cu(1)F6 octahedra and corners with four equivalent V(1)F6 octahedra. The corner-sharing octahedral tilt angles range from 48-63°. There are four inequivalent F sites. In the first F site, F(4) is bonded in a distorted bent 120 degrees geometry to one Rb(1) and two equivalent Cu(1) atoms. In the second F site, F(1) is bonded in a 2-coordinate geometry to two equivalent Rb(1), one V(1), and one Cu(1) atom. In the third F site, F(2) is bonded in a bent 150 degrees geometry to one Rb(1) and two equivalent V(1) atoms. In the fourth F site, F(3) is bonded in a 4-coordinate geometry to two equivalent Rb(1), one V(1), and one Cu(1) atom.
