چکیده
The title compound, [Fe(3)(C(8)H(8)N(2)O)S(2)(CO)(8)], was prepared by the direct reaction of Fe(3)(CO)(12) and 5-meth-oxy-1H-benzoimidazole-2-thiol in tetra-hydro-furan. Desulfurization took place readily to form a sulfide carbonyl cluster. The mol-ecule contains a triangle consisting of three Fe atoms capped by two S atoms above and below. There are two Fe-Fe bonds [2.6322 (5) and 2.5582 (5) Å] in the triangle; the length of the third edge [3.3987 (5) Å] is too long to represent an Fe-Fe bond.

The title compound, [Fe4(C10H15)2(C8H10O4S2)2S4], contains a twisted Fe4S4 cubane-like core. A twofold rotation axis passes through the Fe4S4 core, completing the coordination of the four Fe atoms with two penta-methyl-cyclo-penta-dienyl ligands and two chelating dithiol-ate ligands. There are three short Fe-Fe and three long Fe⋯Fe contacts in the Fe4S4 core, suggesting bonding and non-bonding ...

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 ...

The asymmetric unit of the title compound, [FeCo(2)(C(5)H(5))(2)(C(3)H(3)S(3))S(C(18)H(15)P)(CO)]CF(3)SO(3), consists of a triangular irondicobalt cluster cation and a trifluoro-methane-sulfonate anion. In the cation, the FeCo(2) triangle is symmetrically capped on one face by an S atom and on the other by a C atom linked to a methyl trithio-carbonate residue that bridges the Fe-C bond. Each Co...

The title compound, [Fe(4)(C(5)H(5)OS)(2)S(CO)(12)], was prepared by the direct reaction of Fe(3)(CO)(12) and 2-furyl-methane-thiol in tetra-hydro-furan. Desulfurization took place readily to form an Fe(4)S(3) cluster. The mol-ecule consists of two similar [(μ-2-C(4)H(3)O-CH(2)S)Fe(2)(CO)(6)] moieties joined to a spiro-type four-coordinate μ(4)-S atom such that this bridging sulfur is tetra-hed...

Multidentate naphthyridine-based ligands were used to prepare a series of diiron(II) complexes. The compound [Fe(2)(BPMAN)(mu-O(2)CPh)(2)](OTf)(2) (1), where BPMAN = 2,7-bis[bis(2-pyridylmethyl)aminomethyl]-1,8-naphthyridine, exhibits two reversible oxidation waves with E(1/2) values at +310 and +733 mV vs Cp(2)Fe(+)/Cp(2)Fe, as revealed by cyclic voltammetry. Reaction with O(2) or H(2)O(2) aff...
