The influence of phosphine ligand substituted [2Fe2S] model complexes as electro-catalyst on proton reduction.

ABSTRACT: To probe the influence of phosphine ligand substitution on the well-known [2Fe2S] model, two new [FeFe]-hydrogenase model complexes with the phosphine ligands, PMe₃ or P(CH₃O)₃, were synthesized, such as μ-(SCH(CH₂CH₃)CH₂S)-Fe₂(CO)₅PMe₃1, and μ-(SCH(CH₂CH₃)CH₂S)-Fe₂(CO)₅P(CH₃O)₃2 Confirmation of structures was provided by FTIR, ¹H NMR, ¹³C NMR, ³¹P NMR, elemental analyses and single-crystal X-ray analysis. The crystal structure of complex 2 shows that the P(CH₃O)₃ ligand has less steric effect on the coordination geometry of the Fe atom than the PMe₃ l
