摘要:
The bis(cyclopalladated) tetranuclear compound [{Pd[(eta(5) -C5H5)Fe(eta(5)-C5H3)CMe=N]Cl(PPh3)}(2)] has been prepared and characterized. Proton and P-31 NMR spectra reveal the presence of four diastereomers in solution. The crystal structure of the meso form has been determined by X-ray crystallography. This confirms the existence of two five-membered palladacycles with a sigma(Pd-C-sp2,C-ferrocene) bond. Electrochemical studies, based on cyclic voltammetry, and Mossbauer spectra are also reported.
