A mixed valence {Mn II 3 Mn III Fe II 2 Fe III 2 } cyanide‐bridged molecular cube hosting a caesium cation, CsÌ{Mn 4 Fe 4 }, was synthesized and structurally characterized by X‐ray diffraction. Cyclic‐voltammetry measurements show that its electronic state can be switched between five different redox states, which results in a remarkable electrochromic effect. Magnetic measurements on fresh samples point to the occurrence of a spin‐state change near room temperature, which could be ascribed to a Metal‐to‐Metal Electron Transfer (ET) converting the solely {Fe II ‐CN‐Mn III } pair into a {Fe III ‐CN‐Mn II } pair. This feature was only previously observed in the polymeric MnFe‐PBAs. Moreover, this novel switchable molecule proved to be soluble and stable in organic solvents, paving the way for its integration into advanced materials.
