Diironhexacarbonyl Clusters With Imide and Amine Ligands: Hydrogen Evolution Catalysts
The reaction of Fe 3(CO) 12 and N-(4-thiolphenyl)-1,8- naphthalimide afforded a new diironhexacarbonyl complex (3). The integrity and electronic structure of 3 has been determined by elemental analysis and spectroscopy (NMR and infrared). Infrared spectrum of 3 shows peaks at 2000, 2040, and 2075 cm -1 ascribed to stretching frequencies of the terminal metal carbonyls. Compound 4 was obtained from the reaction of Fe 3(CO) 12 and 4-aminothiolphenol. A comparison of the electronic, electrochemical, and electrocatalytic properties of 3 and 4 are discussed. Cyclic voltammetric studies show that 3 and 4 catalyze the reduction of acetic acid to produce hydrogen at -2.19V and -1.88V versus Fc/Fc +, respectively. © 2011 Taylor & Francis.
