A building unit of Prussian blue was isolated as a cyanide-bridged iron cube of [FeII4FeIII4(CN) 12(tp)8]·12DMF·2Et2O· 4H2O [tp- = hydrotris(pyrazolyl)borate]. A cyclic voltammogram showed quasi-reversible four-stepped redox waves, which correspond to [FeIII4FeII4]/[Fe III5FeII3]+, [Fe III5FeII3]+/[Fe III6FeII2]2+, [Fe III6FeII2]2+/[Fe III7FeII1]3+, and [FeIII7FeII1]3+/[Fe III8]4+ processes. Controlled potential absorption spectral measurements revealed two intervalence charge-transfer bands at 816 and 1000 nm, which were assigned to charge transfers from Fe II ions to adjacent and remote FeIII ions, respectively, in the cube. © 2008 American Chemical Society.
