Neutral and Monocationic Dinuclear (Carbonyl)(cyelopentadienyl)(phenylchalcogenate) Iron Complexes of the General Formulas [(RC5H4)Fe(CO)EPh]_2 and [(RC5H4)Fe(CO)EPh]_2PF6 (E = S or Te; R = H or Me): Synthesis, Molecular Structures, and EPR Spectra

摘要

Heating of the compounds (RC5H4)Fe(CO)_2TePh (R = H (Ⅰ) and Me (Ⅱ)) in heptane afforded the dinuclear complexes [(RC5H4)Fe(CO)TePh]_2 (Ⅲ and Ⅳ, respectively). By oxidation with Fc~+PF_6~-, these complexes were transformed into the paramagnetic cationic complexes [(RC5H4)Fe(CO)TePh]_2PF6 (Ⅴ and Ⅵ, respectively). Structures Ⅲ-Ⅴ and [(C5H5)Fe(CO)SPh]_2PF6 (Ⅶ) were characterized by X-ray diffraction.
