Not a classical spin‐crossover : The heat capacity of the mixed‐valence complex {[( n ‐C 3 H 7 ) 4 N][Fe II Fe III (dto) 3 ]} ∞ (dto=dithiooxalato, see scheme) exhibits a phase transition at 122.4 K as a result of electron transfer, and gives insight into the cooperative phenomena exhibited by the multifunctional material.
