Morrison, Gregory Ramanantoanina, Harry Urland, Werner Smith, Mark D. Loye, Hans-Conrad zur 2015-06-01 Single crystals of uranium(IV)-containing A₂USi₆O₁₅ (A = K, Rb) were grown using the flux growth method. The two compounds crystallize in a new structure type related to Cs₂USi₆O₁₅. K₂USi₆O₁₅ exhibits an interesting crystal-to-crystal transition, which is accompanied by an intense color change. Magnetic properties are reported for A₂USi₆O₁₅ and differ from other U(IV) compounds. A theoretical study on the magnetism of K₂USi₆O₁₅ is reported based on the (UO₆)⁻⁸ clusters. application/pdf https://folia.unifr.ch/global/documents/304402 https://folia.unifr.ch/documents/304402/files/ram_fss.pdf https://folia.unifr.ch/documents/304402/files/ram_fss_sm1.txt https://folia.unifr.ch/documents/304402/files/ram_fss_sm2.txt https://folia.unifr.ch/documents/304402/files/ram_fss_sm3.txt https://folia.unifr.ch/documents/304402/files/ram_fss_sm.pdf eng info:eu-repo/semantics/altIdentifier/doi/10.1021/acs.inorgchem.5b00556 info:eu-repo/semantics/openAccess License undefined Inorganic Chemistry. - 2015, vol. 54, no. 11, p. 5504–5511 info:eu-repo/classification/udc/54 Flux Synthesis, Structure, Properties, and Theoretical Magnetic Study of Uranium(IV)-Containing A₂USi₆O₁₅ (A = K, Rb) with an Intriguing Green-to-Purple, Crystal-to-Crystal Structural Transition in the K Analogue http://purl.org/coar/resource_type/c_6501
