A key challenge in the design of magnetic molecules with intramolecular charge transfer behavior is to obtain reversible magnetic bistability triggered by external stimuli. Here, we show that two dinuclear metal complexes, [(bbp)Fe(CN) 3 Mn(Py 5 Me 2 )]·2.5CH 3 OH ( 4 ) and [(bbp)Fe(CN) 3 Ni(Py 5 Me...
