Iron(I)-carbonyl clusters tethered to (trifluoromethyl)thiophenolates

Crystal and electronic structure of a hexacarbonyldiiron cluster tethered to naphthalene-2-thiolate ligands

“…Selected structural parameters are presented in Table 2. The Fe-Fe bond length is close to that reported for the active site of the hydrogenase enzyme (2.6 Å ) and similar models (Peters et al, 1998;Nicolet et al, 1999;Pandey et al, 2008;Li & Rauchfuss;Haley et al, 2016;Mebi et al, 2012;Pandey et al, 2015). The Fe-S bond linked to the axial naphthalene group is slightly longer, by $0.01 Å , than that linked to the equatorial naphthalene group.…”

Synthesis and structural characterization of iron–sulfur complexes with hydrophilic nitrogen–phosphorus ligands

“…These can be considered as structural and functional models for the active site of [FeFe] hydrogenases [7][8][9][10][11][12][13][14][15][16][17]. Notably, an unusual type of such iron-sulfur complexes with hydrophilic nitrogen-phosphorus ligands, which are regarded as biomimetic models, is of particular interest.…”

Synthesis, Characterization and Electrochemical Studies of bis(Monothiolato) {FeFe} Complexes [Fe2(μ‐SC6H4‐OMe‐m)2(CO)5L] (L = CO, PCy3, PPh3)

“…Only recently, the focus has shifted to monothiolate‐based {FeFe} systems. The limited examples reported include mostly hexacarbonyl and very few phosphine substituted mono‐ or diiron complexes [51–71] . Our group has also reported the redox and electrocatalytic properties of bis(monothiolato)‐based {FeFe} systems [72–77] wherein we have shown that the efficiency and stability of the catalysts vary with the type of monothiolate ligand used.…”
