This paper reports measurements of the XANES spectra of various substituted cerocenes, related trivalent cerocene salts, and some Ce standard compounds in order to determine the formal oxidation state of the Ce ion in substituted cerocenes. The Ce ion in the substituted cerocenes appears to be less electron-rich than in their alkali metal salts, as shown by a 4.5 eV shift toward higher oxidation state of their X-ray K-edges. This argument is supported by structural data which show the Ce ring centroid distance for the substituted cerocenes is {approx}1.97 A as compared to {approx}2.07 A for the K[Ce(COT){sub 2}] diglyme salt. 31 refs., 2 figs.
