Synthesis, Characterization, Optical and Electrochemical Properties of Multinuclear Cobaltadithiolene Complex Derivatives

Abstract

Four new multinuclear cobaltadithiolene complex derivatives [Cp*CoFe2(CO)6(η2, μ3-S2C6H2(SC3H7)2)] 1, [Fe (CpPPh2)2(Cp*CoS2C6H2(SC3H7)2)2] 2, [Cp*CoRu (CO)3(CH2=CHCH2) (η2,μ2-S2C6H2(SC3H7)2)] 3 and [Cp*Co (NSO2C6H4CH3)(S2C6H2(SC3H7)2)] 4 were obtained by reaction of mono-nuclear cobaltadithiolene complex [Cp*CoS2C6H2(SC3H7)2] (Cp*=C5(CH3)5) with Fe3(CO)12, Fe (CpPPh2)2(1,1'-bis (diphenylphosphino) ferrocene), Ru (CO)3(CH2=CHCH2)Br, C6H5I= NSO2C6H4CH3(p)(N-(Phenyliodonio)-p-toluene sulfonamidate), respectively. All new complexes were characterized by C/H analysis,1H NMR, MS and IR spectroscopy. Furthermore, the optical and electrochemical properties of some complexes were also determined by UV-Vis spectra and cyclic voltammogram (CV) analysis.
