Abstract

The homobimetallic hydrazone complex [CpFe(η⁶-p-CH ₃C₆H₄)NHN=C(C₆H₄ -p-CH₃)(η⁵-C₅H₄) FeCp]⁺PF₆ ^- (2) (Cp = η⁵ -C₅H₅) is stereoselectively formed by reaction of the organometallic hydrazine precursor [CpFe(η⁶-p-CH ₃C₆H₄-NHNH₂)]⁺ PF₆ ^- with the sterically demanding p-toluoylferrocene CpFe(η⁵-C₅H₄ )CO(C₆H₄-p-CH₃) (1) in refluxing ethanol. Compound 2 has been fully characterized by IR, UV-vis, and ¹H NMR spectroscopy, cyclic voltammetry and by an X-ray diffraction analysis. The most striking features of the crystal structure are the syn-conformation of the two organometallic units, the long Fe-C_ipso bond distances and the slight cyclohexadienyl character at the coordinated C₆ ring with a folding angle of 6.1°, and that coordinated C₆- and C₅-rings of the binucleating ligand are almost coplanar with a dihedral angle of 8.1°. The crystal structure of the p-toluoylferrocene 1 is also presented.
