A new iron–sulfur cluster compound, namely [(μ‐BNT)Fe 2 (CO) 6 ] ( A ; BNT = ( R )‐1,1′‐binaphthalene‐2,2′‐dithiol), was synthesized by self‐assembly of BNT with [Fe 3 (CO) 12 ] and characterized using 1 H NMR, 13 C NMR, infrared spectra and elemental analysis. The H 2 evolution activity of A was evaluated in a constructed homogeneous photocatalytic system by combining A as catalyst, xanthene dyes as photosensitizer and triethylamine as sacrificial reagent, to give efficient H 2 generation under visible‐light irradiation ( λ > 420 nm). The maximum H 2 evolution of 404 turnovers (versus catalyst) was recorded under optimal conditions in CH 3 CN–H 2 O (1:1, v/v) after 4 h irradiation. The mechanism of H 2 evolution is briefly discussed using fluorescence spectra and electrochemical analysis. Copyright © 2016 John Wiley & Sons, Ltd.
