Cs2MnOF5 crystallizes in the orthorhombic Cmm2 space group. Cs(1) is bonded to two equivalent O(1), two equivalent F(1), four equivalent F(2), and four equivalent F(3) atoms to form distorted CsO2F10 cuboctahedra that share corners with twelve equivalent Cs(1)O2F10 cuboctahedra, faces with six equivalent Cs(1)O2F10 cuboctahedra, and faces with four equivalent Mn(1)F6 octahedra. Mn(1) is bonded to two equivalent F(1), two equivalent F(2), and two equivalent F(3) atoms to form MnF6 octahedra that share corners with two equivalent Mn(1)F6 octahedra and faces with eight equivalent Cs(1)O2F10 cuboctahedra. The corner-sharing octahedra are not tilted. O(1) is bonded in a distorted rectangular see-saw-like geometry to four equivalent Cs(1) atoms. There are three inequivalent F sites. In the first F site, F(1) is bonded in a linear geometry to four equivalent Cs(1) and two equivalent Mn(1) atoms. In the second F site, F(2) is bonded in a single-bond geometry to four equivalent Cs(1) and one Mn(1) atom. In the third F site, F(3) is bonded in a single-bond geometry to four equivalent Cs(1) and one Mn(1) atom.
