Abstract
Abstract: A new series of perovskite-like mixed platinates Ln2MPtO6 (Ln = La, Pr, Nd, Sm, Eu, Gd; M = Mg, Co, Ni, Zn) has been obtained from solid state synthesis. In spite of the difficulty of achieving the formation of pure phases, the crystallographic characterization allows us to point to a GdFeO3 type model with a full 1/1 ordering of the M2+ and Pt4+ cations on the octahedral sites of a distorted ‘ReO3’ network. The results of an X-ray powder Rietveld analysis give evidence of strong crystallochemical similarities with the corresponding iridates and ruthenates. Among the different M2+ cations herein considered, the particular case of Co2+ is emphasized as bringing another proof of the occurrence of its actual size, smaller than modelled.

In spite of the difficulty of achieving the formation of pure phases, the crystallographic characterization allows us to point to a GdFeO3 type model with a full 1/1 ordering of the M2+ and Pt4+ cations on the octahedral sites of a distorted ‘ReO3’ network. The results of an X-ray powder Rietveld analysis give evidence of strong crystallochemical similarities with the corresponding iridates and ruthenates. Among the different M2+ cations herein considered, the particular case of Co2+ is emphasized as bringing another proof of the occurrence of its actual size, smaller than modelled.</abstract><subject lang="en"><genre>Keywords</genre><topic>Perovskites</topic><topic>Platinates</topic><topic>X-ray crystallography</topic></subject><relatedItem type="host"><titleInfo><title>Materials Chemistry and Physics</title></titleInfo><titleInfo type="abbreviated"><title>MAC</title></titleInfo><genre type="journal">journal</genre><originInfo><dateIssued encoding="w3cdtf">199711</dateIssued></originInfo><identifier type="ISSN">0254-0584</identifier><identifier type="PII">S0254-0584(00)X0256-8</identifier><part><date>199711</date><detail type="volume"><number>51</number><caption>vol.</caption></detail><detail type="issue"><number>2</number><caption>no.</caption></detail><extent unit="issue pages"><start>97</start><end>201</end></extent><extent unit="pages"><start>117</start><end>124</end></extent></part></relatedItem><identifier type="istex">132142C5EA4B349270E93ED0C32E9C98ACA8AC30</identifier><identifier type="DOI">10.1016/S0254-0584(97)80279-9</identifier><identifier type="PII">S0254-0584(97)80279-9</identifier><identifier type="ArticleID">97802799</identifier><accessCondition type="use and reproduction" contentType="copyright">©1997 Elsevier Science S.A.</accessCondition><recordInfo><recordContentSource>ELSEVIER</recordContentSource><recordOrigin>Elsevier Science S.A., ©1997</recordOrigin></recordInfo></mods></metadata><serie></serie></istex></record>Pour manipuler ce document sous Unix (Dilib)
