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.
