Bis[1,2-bis(ethoxycarbonyl)ethene-1,2-dithiolato-κ2 S,S′]bis(η5-pentamethylcyclopentadienyl)tetra-μ3-sulfido-diiron(IV)diiron(III)(3 Fe—Fe)

چکیده
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 inter-actions, respectively. The Fe-S bonds in the Fe4S4 core range from 2.1523 (5) to 2.2667 (6) Å and are somewhat longer than the Fe-S bonds involving the dithiol-ate ligand.

The asymmetric unit of the title compound, [Fe4(C6H6O4S2)2(C10H15)2S4]PF6, contains two different complex cations and two PF6 (-) anions. The two complex cations have similar conformations with the butterfly-like Fe4S4 core surrounded by two penta-methyl-cyclo-penta-dienyl ligands and the S atoms of two dithiol-ate ligands. In each Fe4S4 core, there are four short Fe-Fe and two long Fe⋯Fe conta...

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...

In the title polymeric Cu(I) compound, [Cu(2)Br(2)(C(12)H(10)N(2))](n), the Cu cation is coordinated by an N atom from the 1,2-bis-(4-pyrid-yl)ethene ligand and three Br(-) anions in a distorted tetra-hedral CuBr(3)N coordination geometry. Each Br(-) anion bridges three Cu cations related by inversion centers, forming a stair-like polymeric chain along the a axis, and the terminal N atoms of th...
