Abstract: The electrochemical reduction processes of [Fe(H_2O)_3(NCS)_3] (18-C-6) have been studied in nonaqueous media by method of cyclic voltammetry and spectroelec-trochemistry at an optical transparent thin layer electrode. The formal potential, E°′, electron transfer number, n, diffusion cofficient, D_O, formal heterogeneous electron transfer rate constant, k_S′, and electrochemical transfer coefficient, a, are deter-minated. Significant effect of solvents on the electrochemical behaviors has been observed. The higher the β, the higher the thermodynamic and kinetic stabilities of the coordination compound resulted.
