The phase retains the trigonal symmetry and the P3m1 space group of the parent compound with cell parameters a = 3.96671(10) A and c = 6.8214(2) A and Z = 1. Refinements of 46 parameters by the Rietveld method, using 80 (X-ray) and 138 (neutron) reflections, led to Rp = 0.102 and R wp = 0.129 (X-ray), Rp = 0.063 and R wp = 0.048 (neutron), R p = 0.086 and R wp = 0.113 (global). The oxidation process is shown to correspond to an insertion of oxygen anions in the hexagonal prismatic bipyramidal cavity of the host structure. These additional oxygen atoms occupy a well defined off centered position of the cage, thereby forming short Ce-O and O-O distances. However, due to the disordered nature of the structure, no precise O-O distances and therefore phase charge balance information have been established.","PeriodicalId":23855,"journal":{"name":"Zeitschrift für Kristallographie - Crystalline Materials","volume":"10 1","pages":"24 - 28"},"PeriodicalIF":0.0,"publicationDate":"1997-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75509597","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
