摘要
A central role for the alkali metal cation was determined in the thermally activated electron transfer CoIII(LS)-FeII(LS) ⇋ CoII(HS)-FeIII(LS) in a CsCoFe Prussian blue derivative by localizing the alkali metal ion and identifying its interactions with the surrounding network in the high- and low-temperature states (see scheme).
