Abstract

The neutral air-sensitive Fe(II) hydrazonyl complex CpFe{(η-C ₆H₅)NN=CHC₆H₄-p-NMe₂} (2) is obtained by deprotonation of its cationic hydrazone precursor [CpFe{(η⁶-C₆H₅)NHN=CHC₆H ₄-p-NMe₂}]⁺PF₆^- (1) with t-BuOK in tetrahydrofuran. The spectroscopic data, the X-ray molecular structure, and a DFT MO analysis revealed that 2 is best described as a hybrid of η⁵-iminocyclohexadienyl and η⁶-zwitterionic complexes.
