摘要：

Synchrotron radiation was used to determine the oxidation state of cerium in Ce2MoO6 through Ce L-edge X-ray absorption fine structure (XAFS). The results from this direct spectroscopic investigation reveal that, to the level of sensitivity of the technique, cerium is trivalent in Ce2MoO6. Magnetic susceptibility data over the temperature range 10-300 K do not follow the Curie Law and, therefore, cannot be used to support any assignment of valence. The possible origins of the unique structure and colour of the RE = Ce analogue of the RE2MoO6 series are discussed.
