Abstract:: The NMR and FT-IR Spectra of ten (eta C₆H₉CRR'-Cp)₂MCl₂(M=Ti, Zr) were measured. The constructions of the compounds were identified by ¹H NMR and ¹³C NMR spectra. All complexes are bonded by M-Cp through center of Cp. The influence of the center metal atoms and the substituents upon the NMR and FT-IR spectra were discussed.
Key words:: (eta C₆H₉CRR'-Cp)₂MCl₂(M=Ti, Zr); ¹H NMR; ¹³C NMR; FT-IR spectra; vibration modes; assign
