Two tetra-iron complexes with bridging diphosphine ligands, named [Fe₄(CO)₁₀(μ-SCH₂CH(CH₃)S)₂(dppa)] (1) and [Fe₄(CO)₁₀(μ-SCH₂CH(CH₃)S)₂(trans-dppv)] (2), where dppa=bis(diphenylphosphino)acetylene and trans-dppv= trans-1, 2-bis(diphenylphosphino)ethylene, were prepared by the reaction of complex [Fe₂(CO)₆(μ-SCH₂CH(CH₃)S)] with dppa or trans-dppv. Both complexes were structurally identified by elemental analysis, FTIR spectra, ¹H NMR, and ³¹P NMR, together with single-crystal X-ray diffraction analysis. X-ray crystallographic studies revealed that complex 1 consists of two di-iron propane-1, 2-dithiolate pentacarbonyl sub-units connected by a linear dppa ligand whereas a zigzag trans-dppv ligand is found in complex 2. The electrochemical properties were probed by cyclic voltammetry, showing that two irreversible reductions and one irreversible oxidation were found for both complexes. Furthermore, electrocatalytic studies were carried out by adding acetic acid as a proton source into the solution. The results demonstrated that both complexes can catalyze proton reduction to evolve hydrogen. For comparison, the catalytic efficiency of complex 2 was better than complex 1.
