A new iron–sulfur cluster compound, namely [(μ-BNT)Fe₂(CO)₆] (; BNT = (R)-1,1′-binaphthalene-2,2′-dithiol), was synthesized by self-assembly of BNT with [Fe₃(CO)₁₂] and characterized using ¹H NMR, ¹³C NMR, infrared spectra and elemental analysis. The H₂ evolution activity of was evaluated in a constructed homogeneous photocatalytic system by combining as catalyst, xanthene dyes as photosensitizer and triethylamine as sacrificial reagent, to give efficient H₂ generation under visible-light irradiation (λ > 420 nm). The maximum H₂ evolution of 404 turnovers (versus catalyst) was recorded under optimal conditions in CH₃CN–H₂O (1:1, v/v) after 4 h irradiation. The mechanism of H₂ evolution is briefly discussed using fluorescence spectra and electrochemical analysis. Copyright
