Rb2MnF5 crystallizes in the tetragonal P4/mmm space group. Rb(1) is bonded in a distorted q6 geometry to two equivalent F(1) and eight equivalent F(2) atoms. Mn(1) is bonded to two equivalent F(1) and four equivalent F(2) atoms to form corner-sharing MnF6 octahedra. The corner-sharing octahedra are not tilted. There are two 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.
