Tri-μ-ethanethiolato-bis{[η5-1,2,3,4-tetramethyl-5-(trimethylsilyl)cyclopentadienyl]iron(II,III)}(FeII–FeIII)

چکیده
The title complex, [Fe(2)(C(2)H(5)S)(3)(C(12)H(21)Si)(2)], has an unusual Fe(2)S(3) core. The two 1,2,3,4-tetra-methyl-5-(trimethyl-silyl)cyclo-penta-dienyl (Cp') ligands coordinate to the Fe atoms with their C(5) planes perpendicular [dihedral angles = 88.23 (7) and 88.55 (7)°] to the Fe-Fe vector, building two Cp'Fe subunits. These two subunits are bridged by three thiol-ate ligands. There are no significant differences in the coordination geometries between the two Fe atoms. The short Fe-Fe distance of 2.7842 (5) Å is clear evidence of an inter-metallic bond. Such a diiron-sulfur structure might act as a model of active sites in some metalloproteins.

The asymmetric unit of the title compound, [Fe(2)(C(5)H(5))(2)(C(2)H(8)N(2))(CO)(4)](BF(4))(2), contains two half-cations, each located on a center of symmetry, and two tetra-fluorido-borate anions. The iron atoms adopt a three-legged piano-stool geometry. All amine H atoms are involved in N-H⋯F hydrogen bonds, which consolidate the crystal packing along with weak C-H⋯O and C-H⋯F inter-actions.
