Dinuclear Iron Compounds with Hydrocarbon Ligands

Unexpected fragmentation of phenyldithiobenzoate, formation and X-ray structure of [μ,η2(S,S)-1,2-(dithio)-1,2-(diphenylethylene)] diiron hexacarbonyl complex

“…The thermal reaction of Fe 2 (CO) 9 with organic substrates that contain sulfur atoms is a general synthetic way to various hexacarbonyldiiron coordination compounds [1]. Some complexes containing a Fe 2 S 2 core attract interest of chemists because they have a close resemblance to the diiron unit of the FeFe-hydrogenase [2,3].…”

“…In order to understand this reaction, we investigated the electrochemical behavior of dithioester 1, complexes 2 or 3 and 5 and we report here our results. 1 H and 13 C NMR spectra were recorded at 60 and 20.115 MHz, respectively, in CDCl 3 with TMS as internal standard. Mass spectra were recorded with a Varian MAT 311 spectrophotometer at 70 eV at CRMPO (Rennes, France).…”

Synthesis, characterization, and structural study of iron–sulfur core {Cp2Fe2(μ-SEt)2} complexes

“…The studies on the synthetic model complexes containing iron-sulfur core not only provide a better understanding of the biological molecules but also provide fundamental knowledge in iron-sulfur coordination chemistry, which is necessary for a deeper understanding of iron containing non-heme enzymes. Among synthetic iron-sulfur complexes, dinuclear cyclopentadienyl thiolate-bridged species are a well-established class of compounds [2,9]. A series of studies on the iron-sulfur core {Cp 2 Fe 2 (l-SR) 2 } complexes (R = alkyl or aryl), of their redox and/or their crystal structures have reported [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25].…”

[2Fe–2S] Cluster Supported by Redox-Active o-Phenylenediamide Ligands and Its Application toward Dinitrogen Reduction

“…The pattern in these metric parameters suggests that the pda ligands are open-shell π-radical anions Xyl pda •– ( S = 1 / 2 ). The intramolecular Fe–Fe distance [2.633(1) Å] is slightly longer than the sum of the covalent radii (2.50 Å) . The solution magnetic moment of 2 is 1.2 μ B in THF- d 8 at 25 °C using the Evans method, close to an S Total = 0 ground state.…”
