Abstract: Two novel diferrocenyl thiourea derivatives FcL1 and FcL2 were synthesized. The structures of the compounds were determined by elemental analysis, IR and 1H NMR spectra. The X-ray single crystal structure analysis of FcL1 indicates that the crystal belongs to triclinic system, P1 space group, there was a hydrogen bond in the compound. It was found that the electrochemical property of FcL1 was very similar with that of FcL2, the redox couple(FcL1: E1/2=600 mV; FcL2: E1/2=605 mV) was corresponding to the progress of 2Fc3++2e-2Fc2+, which can be rationalized by the equivalent environment of the ferrocene subunit in each case. The difference between m-ferrocenylaniline and p-ferrocenylaniline didn't cause the distinct change for their diffusion coefficient(D), but caused the distinct change for their electrochemical reaction rate constant(ks).
