The reduction of dinitrogen to ammonia is catalyzed by a molybdenum nitrogenase. Several model compounds of this enzyme: (a) Linear cluster I, [(C6H5)4P]2[Cl2FeS2MoS2FeCl2]; (b) Linear cluster II, [(C6H5)4P]2[S2MoS2FeCl2]; (c) Single cubane cluster, [MoFe3S4(Et2dtc)5].DMF were synthesized and characterized. Then investigated by in situ FTIR spectroelectrochemical method. The acquisition of FTIR spectra of these compounds was conducted on the electrochemical system during the potential step chronoamperometry process. The recorded spectra were analyzed. The isotope 34S-substituted compound of linear cluster I was synthesized and investigated by in situ FTIR spectroelectrochemical method. Resonance Raman spectra of linear cluster I, isotope 34S-substituted cluster I and their chemical reduced product were obtained in order to deduce useful information of structure change during the redox reaction.
