Abstract The formation of the previously unknown [(C5H4CPh2)2Ru]2+ dication was established by1H and13C NMR spectroscopy. This cation readiiy hydrolizes to form the monocation, [Ph2(HO)CC5H4RuC5H4CPh2]+. The latter was characterized by NMR spectroscopy and X-ray structural analysis. For comparison, [C5H5RuC5H4CPh2]+PF6 − was also studied by X-ray structural analysis. The increase in the M-Cα distance and the decrease in the angle of inclination of the CPh2 group to the metal atom in disubstituted ruthenocene compared to those in monosubstituted ruthenocene is related to the presence of a bulky substituent in the second Cp ligand and is likely due to the crystal packing effect. IR spectra and X-ray structural analysis attest to the existence of the OH ⋯ OSO2CF3 hydrogen bond in crystals of the trifluoromethanesulfonate monocation.
