The most promising approach is breeding of new tritium within the operating fusion reactor. For this purpose, suitable breeding materials are needed. Lithium beryllium oxides are a promising class of compounds, as they unite both target and neutron multiplier in one material. While there have already been studies on sintered ceramics in the Li<jats:sub>2<\/jats:sub>O\u00b7BeO system, the crystal structure of compounds of a defined composition has so far remained unsolved. Herein, we report on the synthesis of phase\u2010pure Li<jats:sub>2<\/jats:sub>Be<jats:sub>2<\/jats:sub>O<jats:sub>3<\/jats:sub> in a high\u2010temperature (HT) approach and its structure determination by single\u2010crystal X\u2010ray diffraction (sc\u2010XRD). In addition, the compound was characterized by powder X\u2010ray diffraction (PXRD), solid\u2010state nuclear magnetic resonance (NMR) spectroscopy, and elemental analysis. The thermal stability, which is important for use as blanket material in a fusion reactor, was examined with differential scanning calorimetry (DSC).<\/jats:p>","DOI":"10.1002\/chem.202502209","type":"journal-article","created":{"date-parts":[[2025,8,11]],"date-time":"2025-08-11T10:49:32Z","timestamp":1754909372000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Long Used but Hardly Known: Synthesis and Crystal Structure of Tritium Breeding Li<sub>2<\/sub>Be<sub>2<\/sub>O<sub>3<\/sub>"],"prefix":"10.1002","volume":"31","author":[{"given":"Georg","family":"Krach","sequence":"first","affiliation":[{"name":"Department of Chemistry University of Munich (LMU)  Butenandtstra\u00dfe 5\u201313 Munich 81377 Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-7261-1171","authenticated-orcid":false,"given":"Jennifer","family":"Steinadler","sequence":"additional","affiliation":[{"name":"Department of Chemistry University of Munich (LMU)  Butenandtstra\u00dfe 5\u201313 Munich 81377 Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Robert","family":"Calaminus","sequence":"additional","affiliation":[{"name":"Department of Chemistry University of Munich (LMU)  Butenandtstra\u00dfe 5\u201313 Munich 81377 Germany"},{"name":"Max Planck Institute for Solid State Research  Heisenbergstra\u00dfe 1 Stuttgart 70569 Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3094-303X","authenticated-orcid":false,"given":"Bettina V.","family":"Lotsch","sequence":"additional","affiliation":[{"name":"Department of Chemistry University of Munich (LMU)  Butenandtstra\u00dfe 5\u201313 Munich 81377 Germany"},{"name":"Max Planck Institute for Solid State Research  Heisenbergstra\u00dfe 1 Stuttgart 70569 Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4571-8035","authenticated-orcid":false,"given":"Wolfgang","family":"Schnick","sequence":"additional","affiliation":[{"name":"Department of Chemistry University of Munich (LMU)  Butenandtstra\u00dfe 5\u201313 Munich 81377 Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2025,8,11]]},"reference":[{"key":"e_1_2_9_1_1","doi-asserted-by":"publisher","DOI":"10.1002\/ese3.43"},{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0022-3115(01)00442-1"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.fusengdes.2015.10.024"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.fusengdes.2015.07.021"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.13182\/FST05-A734"},{"key":"e_1_2_9_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.fusengdes.2022.113116"},{"key":"e_1_2_9_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jnucmat.2020.152593"},{"key":"e_1_2_9_8_1","doi-asserted-by":"publisher","DOI":"10.2172\/4175781"},{"key":"e_1_2_9_9_1","doi-asserted-by":"publisher","DOI":"10.1021\/ic50050a038"},{"key":"e_1_2_9_10_1","doi-asserted-by":"publisher","DOI":"10.1002\/zaac.19754150308"},{"key":"e_1_2_9_11_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.fusengdes.2013.05.013"},{"key":"e_1_2_9_12_1","doi-asserted-by":"publisher","DOI":"10.1023\/A:1004122013795"},{"key":"e_1_2_9_13_1","unstructured":"Deposition Number 2448732 (for Li2Be2O3) contains the supplementary crystallographic data for this paper.
