K2MnF6 crystallizes in the cubic Fm-3m space group. K(1) is bonded to twelve equivalent F(1) atoms to form KF12 cuboctahedra that share corners with twelve equivalent K(1)F12 cuboctahedra, faces with six equivalent K(1)F12 cuboctahedra, and faces with four equivalent Mn(1)F6 octahedra. Mn(1) is bonded to six equivalent F(1) atoms to form MnF6 octahedra that share faces with eight equivalent K(1)F12 cuboctahedra. F(1) is bonded in a single-bond geometry to four equivalent K(1) and one Mn(1) atom.
