We applied the recently developed low-dose electron diffraction tomography method to solve the structure by direct methods. The obtained structure model contains all 9 independent cation positions and all 13 oxygen positions. A subsequent refinement against powder X-ray diffraction data ascertained the high quality of the structure solution, in particular, the unusual structural arrangement that there are three different environments for Ge in this phase.<\/jats:p>","DOI":"10.1107\/s2052520620008914","type":"journal-article","created":{"date-parts":[[2020,8,13]],"date-time":"2020-08-13T16:47:30Z","timestamp":1597337250000},"page":"727-732","update-policy":"https:\/\/doi.org\/10.1107\/cm_01","source":"Crossref","is-referenced-by-count":3,"title":["Three different Ge environments in a new Sr<sub>5<\/sub>CuGe<sub>9<\/sub>O<sub>24<\/sub>phase synthesized at high pressure and high temperature"],"prefix":"10.1107","volume":"76","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6904-2319","authenticated-orcid":true,"given":"Holger","family":"Klein","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"St\u00e9phanie","family":"Kodjikian","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"R\u00e9my","family":"Philippe","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1556-2095","authenticated-orcid":true,"given":"Lei","family":"Ding","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Claire V.","family":"Colin","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0812-6850","authenticated-orcid":true,"given":"C\u00e9line","family":"Darie","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1488-2257","authenticated-orcid":true,"given":"Pierre","family":"Bordet","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"329","published-online":{"date-parts":[[2020,8,12]]},"reference":[{"key":"je5030_bb1","doi-asserted-by":"crossref","first-page":"306","DOI":"10.1107\/S1600576715001132","volume":"48","author":"Burla","year":"2015","journal-title":"J.
