| Abstract: | In order to create photoactive catalysts for hydrogen production, a novel trimetallic Re–Fe2S2 complex 4 was synthesized by the coordination of the free –PPh2 group of the ligand of the rhenium photosensitizer 6 to an azadithiolate (ADT)-bridged diiron complex 8 with the assistance of the decarbonylation reagent Me3NO. Complex 4 was characterized by 1H, 13C, 31P NMR and HRMS spectra. The IR, UV–vis and electrochemical data indicate some interactions between Re and Fe2S2 moieties, and the photo-induced electron transfer from the excited state of the Re moiety to the Fe2S2 catalyst is thermodynamically feasible. |
