RbCoCuF6 crystallizes in the orthorhombic Imma space group. The structure is three-dimensional. Rb1+ is bonded to six F1- atoms to form RbF6 octahedra that share corners with six equivalent CoF6 octahedra and corners with six equivalent CuF6 octahedra. The corner-sharing octahedra tilt angles range from 67–68°. There are five shorter (3.10 Å) and one longer (3.17 Å) Rb–F bond lengths. Co3+ is bonded to six F1- atoms to form CoF6 octahedra that share corners with two equivalent CoF6 octahedra, corners with four equivalent CuF6 octahedra, and corners with six equivalent RbF6 octahedra. The corner-sharing octahedra tilt angles range from 44–68°. There is four shorter (1.93 Å) and two longer (1.98 Å) Co–F bond length. Cu2+ is bonded to six F1- atoms to form CuF6 octahedra that share corners with two equivalent CuF6 octahedra, corners with four equivalent CoF6 octahedra, and corners with six equivalent RbF6 octahedra. The corner-sharing octahedra tilt angles range from 45–68°. There is two shorter (1.96 Å) and four longer (2.03 Å) Cu–F bond length. There are three inequivalent F1- sites. In the first F1- site, F1- is bonded in a 2-coordinate geometry to one Rb1+ and two equivalent Co3+ atoms. In the second F1- site, F1- is bonded in a 2-coordinate geometry to one Rb1+ and two equivalent Cu2+ atoms. In the third F1- site, F1- is bonded in a 2-coordinate geometry to one Rb1+, one Co3+, and one Cu2+ atom.
