In this paper, the electrochemical cyclic voltammetry,UV/Vis and in situ FTIR spectroscopy were used to study the electrochemical reduction of [Os-VI (N)(NH3)(4)](CF3SO3)(3) on GC and Pt electrode in acetonitrile. The results demonstrated that the N-N coupling can occur between [Os-VI(N)(NH3)(4)](3+) and the osmium(V) species generated at the electrode. It has revealed for the first time,by in situ FTIR spectroscopy, that the IR absorption of the nu>(*) over bar * (N=N) mode of the mu -dinitrogen osmium [III, II] and [II, II] complex yields positive-going band at around 2 019 cm(-1) and negative-going band near 1 970 cm(-1),respectively. The results provided new insights in understanding the mechanism of the coupling reaction [Os-V=N] [Os-VI=N][Os-VI=N]<=>[Os-II-N=N-Os-II].
