| Abstract: | 99Ru Mössbauer spectra at 5 K have been measured on samples of salts of ruthenocene with halogens, expressed as Ru(C5H5)2X]Y (X=Cl, Br, Y=PF6, and X=1, Y=13). The values of both the isomer shift and the quadrupole splitting of these salts with halogens are larger compared to those of ruthenocene. It is concluded that ruthenocene gives salts having direct chemical bonding between Ru and Cl, Br, or I, and that the Ru atom in each salt is in a higher oxidation state than 2+ in ruthenocene. |
