Rb2MnOF5 crystallizes in the orthorhombic Cmcm space group. Rb(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 RbO2F10 cuboctahedra that share corners with twelve equivalent Rb(1)O2F10 cuboctahedra, faces with six equivalent Rb(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 Rb(1)O2F10 cuboctahedra. The corner-sharing octahedral tilt angles are 3°. O(1) is bonded in a rectangular see-saw-like geometry to four equivalent Rb(1) atoms. There are three inequivalent F sites. In the first F site, F(1) is bonded in a distorted linear geometry to four equivalent Rb(1) and two equivalent Mn(1) atoms. In the second F site, F(2) is bonded in a single-bond geometry to four equivalent Rb(1) and one Mn(1) atom. In the third F site, F(3) is bonded in a distorted single-bond geometry to four equivalent Rb(1) and one Mn(1) atom.
