SummaryWe present a relatively simple inorganic system of two co-crystallized synthetic iron complexes with remarkably complex electronic structures, owing to the large number of possible redox states at the metal centers as well as at the redox-active ligands. For the first time an unprecedented complex reversible phase transition at 235 K is observed. With this model the exploration of complex processes, which may happen in similar ways in biological systems, is demonstrated by combined experimental techniques.
