Three basic organometallic compounds, Fe(phen)/sub 2/(CN)/sub 2/, Cp/sub 4/Fe/sub 4/(CO)/sub 4/, and CpFe(CO)/sub 2/CN, were studied in the AlCl/sub 3//n-butylpyridinium chloride, BPC, molten-salt system. IR and UV-VIS spectroscopy show that the ligands of all three complexes interact with Lewis acids contained in the melts. Comparison of spectral shifts for these compounds in the various melts with shifts previously reported for isolated Lewis acid adducts of the same compounds provides insight into the relative electron pair acceptor ability of the various melts. Cyclic voltammetry of Fe(phen)/sub 2/(CN)/sub 2/ in the molten salts demonstrates a very large shift in the oxidation potential with increasing acidity whereas the oxidation potential of Cp/sub 4/Fe/sub 4/(CO)/sub 4/ is unchanged. This behavior is consonant with simple molecular orbital calculations.
