Iron complexes thiolato

Ferrocene compounds containing heteroelements are versatile building blocks for polynuclear complexes. They possess electrochemically active iron centers as well as unique cylindrical shapes. An example of ferrocene-substituted thiolato ligands is l,l -ferrocenedithiolate (S2fc). Its complex with Pd(II) lacks a Pd—Fe bond. 

In conclusion, the presented dinuclear iron structure is the first example of a bio-mimetic iron compound, which can be regarded as a first generation model for the class of [Fe]-only hydrogenases. The complex incorporates both relevant carbon monoxide ligands, as well as three bridging thiolato ligands, which could be possibly present in the active site of these enzymes. 

The iron-thiolato complex (Me4N)2[Fe4S4(SC6H5)4] crystallizes in this space group with Z = 4, and the asymmetric unit consists of two Me4N+ cations and... 

Tetrakis(thiolato)tetra-/u3-thio-tetrairon, [Fe4S4(SR)4]2", complexes involve a distorted cubane-type structure with a thiolato group completing an essentially tetrahedral array of sulfur atoms about each iron. These moieties are close structural analogs of the iron-sulfur centers of oxidized four- and eight-iron...

A synthetic iron porphyrin with a thiolato ligand in the axial position has been oxidized by hydrogen peroxide in the presence of chloride. The shift of the Soret band from 408 nm to 404 nm might be due to the formation of a putative Fe OCl entity which can generate free HOCl after protonation. " The kinetic parameters of halide oxidation by a high-valent manganese-oxo porphyrin complex have been reported. ... 

Chemical reactions such as protonation or electron transfer reactions of transition metal complexes can occur either at the metal center or at one of the ligands. Factors governing this ligand vs metal reactivity are not clear and it appears worthwhile to gain information in this area. In this respect, transition metal thiolato complexes are an important family of compounds. For example, the iron derivatives CpFe(CO)2SAr have been shown to react with electrophiles via the sulfiir lone pair, suggesting that the HOMO has a strong sulfur 3d character. This was also confirmed by the structure of the dicationic dimer obtained upon one electron oxidation ...
