چکیده
The title compound, [Fe(C(4)H(2)N(2)S(2))(C(3)H(9)P)(2)(CO)(2)], was obtained as a mononuclear by-product during the treatment of [Fe(2)(μ-S(2)C(4)N(2)H(2))(CO)(6)] in excess trimethyl-phosphane. The Fe atom is six-coordinated by two thiol-ate S atoms, two phosphane P atoms and two carbonyl C atoms in a distorted octa-hedral geometry. The average Fe-C(O) distance (1.771 Å) is relatively shorter than that of its parent hexa-carbonyl-diiron compound, and differs by 0.511 Å from the average Fe-P(Me)(3) distance. The five-membered FeC(2)S(2) chelate ring plane is close to being perpendicular to the P/Fe/P plane [86.5 (2)°].

The title compound, [Fe(2)(C(3)H(6)S(2))(C(18)H(15)P)(2)(CO)(4)], which might serve as an active-site model of [FeFe]-hydrogenase, contains two fused Fe/S/C/C/C/S six-membered rings, one of which has a chair conformation and the other a boat conformation. Each Fe atom is coordinated by two carbonyl ligands, a triphenyl-phosphane ligand and a bis-bidentate dithiol-ate ligand, and also forms an F...

In the title compound, [Fe(2)(C(4)H(2)N(2)S(2))(C(3)H(9)P)(CO)(5)], the Fe(2)S(2) core adopts a butterfly conformation. The PMe(3) ligand is coordinated in the basal position, roughly cis to the Fe-Fe bond. The Fe-Fe distance of 2.4970 (6) Å is relatively short compared to those (ca 2.53 Å) found in another monosubstituted diiron compound. A rigid planar dithiol-ate bridge is featured, with an ...
