Abstract

The synthesis of [K]₂[CpFe(CN)₃] (1) and its pentamethylcyclopentadienyl analog (2) has been described via the photolysis of the corresponding [K][CpFe(CO)(CN)₂] salts in methanol in the presence of KCN. The structure of complex 1 has been characterized by means of X-ray crystallography, where the potassium ions are interacting with the N atoms of the cyanide ligands. As expected, the average ν_CN stretching frequency in the CpFe(CN)3- anion is 16 cm^-1 higher than that in the more electron-donating pentamethylcyclopentadienyl derivative.
