A rad. dad : The electronic structure of [Fe(dad) 3 ][Fe(pda) 2 ] was investigated by X‐ray crystallography, Mössbauer spectroscopy, and magnetic susceptibility measurements as a function of the temperature. Reversible one‐electron transfer from the dianion (high‐spin Fe II ) to the dication (low‐spin Fe II ) generates a monoanion (intermediate‐spin Fe III ) and a monocation (high‐spin Fe II and α‐diimine π radical anion) above 235 K.
