CsMnVF6 crystallizes in the orthorhombic Imma space group. The structure is three-dimensional. Cs1+ is bonded to six F1- atoms to form CsF6 octahedra that share corners with six equivalent VF6 octahedra and corners with six equivalent MnF6 octahedra. The corner-sharing octahedra tilt angles range from 66–72°. There are a spread of Cs–F bond distances ranging from 3.19–3.49 Å. V3+ is bonded to six F1- atoms to form VF6 octahedra that share corners with two equivalent VF6 octahedra, corners with four equivalent MnF6 octahedra, and corners with six equivalent CsF6 octahedra. The corner-sharing octahedra tilt angles range from 37–72°. There is four shorter (1.96 Å) and two longer (1.99 Å) V–F bond length. Mn2+ is bonded to six F1- atoms to form MnF6 octahedra that share corners with two equivalent MnF6 octahedra, corners with four equivalent VF6 octahedra, and corners with six equivalent CsF6 octahedra. The corner-sharing octahedra tilt angles range from 43–71°. There are two shorter (2.09 Å) and four longer (2.14 Å) Mn–F bond lengths. There are three inequivalent F1- sites. In the first F1- site, F1- is bonded in a bent 150 degrees geometry to one Cs1+ and two equivalent V3+ atoms. In the second F1- site, F1- is bonded in a 3-coordinate geometry to one Cs1+ and two equivalent Mn2+ atoms. In the third F1- site, F1- is bonded in a 2-coordinate geometry to one Cs1+, one V3+, and one Mn2+ atom.
