Triiron Complexes Featuring Azadiphosphine Related to the Active Site of [FeFe]-Hydrogenases: Their Redox Behavior and Protonation.

ABSTRACT: The design of iron clusters featuring a bimetallic core and several protonation sites in the second coordination sphere of the metal centers is important for modeling the activity of polymetallic active sites such as the H-cluster of [FeFe]-hydrogenases. For this purpose, the syntheses of complexes [Fe₃(CO)₅(κ²-P^Ph₂N^R₂)(μ-pdt)₂] (R = Ph (1), Bn (2)) and [Fe₃(CO)₅(κ²-P^Ph₂N^R₂)(μ-adt^Bn)(μ-pdt)] (R = Ph (3), Bn (4)) were carried out by reacting hexacarbonyl precursors [Fe₂(CO)₆(µ-xdt)] (xdt = pdt (propanedithiolate), adt^Bn
