RbCoCrF6 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 CrF6 octahedra and corners with six equivalent CoF6 octahedra. The corner-sharing octahedra tilt angles range from 66–70°. There are a spread of Rb–F bond distances ranging from 3.09–3.29 Å. Cr3+ is bonded to six F1- atoms to form CrF6 octahedra that share corners with two equivalent CrF6 octahedra, corners with four equivalent CoF6 octahedra, and corners with six equivalent RbF6 octahedra. The corner-sharing octahedra tilt angles range from 41–70°. There is four shorter (1.94 Å) and two longer (1.97 Å) Cr–F bond length. Co2+ is bonded to six F1- atoms to form CoF6 octahedra that share corners with two equivalent CoF6 octahedra, corners with four equivalent CrF6 octahedra, and corners with six equivalent RbF6 octahedra. The corner-sharing octahedra tilt angles range from 45–69°. There are two shorter (2.01 Å) and four longer (2.07 Å) Co–F bond lengths. There are three inequivalent F1- sites. In the first F1- site, F1- is bonded in a distorted bent 150 degrees geometry to one Rb1+ and two equivalent Cr3+ atoms. In the second F1- site, F1- is bonded in a 3-coordinate geometry to one Rb1+ and two equivalent Co2+ atoms. In the third F1- site, F1- is bonded in a 2-coordinate geometry to one Rb1+, one Cr3+, and one Co2+ atom.
