- The preparation and characterization of two novel amino-incorporated sulfur-bridged dinuclear iron (I) complexes of the type [NR(mu-SCH2)2]Fe-2(CO)(6), one being amino protected [N(CH2CH2NHTs)(mu-SCH2)(2)]Fe-2(CO)(6) (8) and the other [(mu-SCH2)(2)Fe-2(-CO)(6)NCH2CH2N (mu-SCH2)(2)]Fe-2(CO)(6) (9) are described. These two complexes are readily prepared in a S(N)2 manner between double lithium anion and bis(chloromethyl) amine derivatives. The structures of 8 and 9 were characterized by IR, H-1, C-13 NMR, MS and HRMS spectra and further determined by X-ray analyses. Protonation of complex 8 gave the mono N-protonated product, while for 9 the protonation occurred in both of the N atoms. The redox properties were evaluated by cyclic voltammograms. It was shown that these two complexes can catalyze electrochemical reduction of proton to molecular hydrogen.
