| Abstract Scope |
Uranium chalcogenides have a unique ability to stabilize uranium’s paramagnetic 4+ oxidation state, making it possible to study the magnetic behavior of uranium(IV). However, the high oxophilicity of uranium inevitably leads to the reaction of uranium with even trace amounts of oxygen present, resulting in uranium oxide or magnetic oxychalcogenide impurities that complicate magnetic measurements. Our recently established boron−chalcogen mixture (BCM) method permits the synthesis of uranium chalcogenides starting from oxide reagents by adding a mixture of boron and the desired chalcogen to the reagent mixture, resulting in products devoid of actinide oxide or oxychalcogenide impurities. This talk will introduce the BCM method and describe the synthesis, characterization, and magnetic properties of some A2M4U6S17 (A = K, Rb, Cs; M = Pd, Pt) compounds and 2H perovskite related uranium chalcogenides with the chemical formula Ba3MUQ6 ( M = transition metal; Q = S, Se), all synthesized utilizing the BCM method. |
