Abstract
Sm2Mo2O3.83N3.17, the first molybdenum oxynitride pyrochlore, was synthesized by heating the Sm2Mo2O7 pyrochlore in flowing ammonia at 625°C for 24 hours. Sm2Mo2O3.83N3.17 forms with the cubic pyrochlore structure, space group Fd3m (a = 10.4975 إ). The sample is semiconducting and the temperature-dependent magnetic susceptibility follows Curie-Weiss behavior. X-ray absorption near-edge spectroscopy measurements indicate that in the oxynitride, molybdenum has a formal oxidation state significantly larger than 4+.
