Herein, we report on the highly condensed wurtzite\u2010type Be<jats:sub>2<\/jats:sub>PN<jats:sub>3<\/jats:sub>, which was synthesized from Be<jats:sub>3<\/jats:sub>N<jats:sub>2<\/jats:sub> and P<jats:sub>3<\/jats:sub>N<jats:sub>5<\/jats:sub> in a high\u2010pressure high\u2010temperature approach at 9\u2005GPa and 1500\u2009\u00b0C. It is the missing member in the row of formula type <jats:italic>M<\/jats:italic><jats:sub>2<\/jats:sub>PN<jats:sub>3<\/jats:sub> (<jats:italic>M\u00a0<\/jats:italic>=\u00a0Mg, Zn). The structure was elucidated by powder X\u2010ray diffraction (PXRD), revealing that Be<jats:sub>2<\/jats:sub>PN<jats:sub>3<\/jats:sub> is a double nitride, rather than a nitridophosphate. The structural model was further corroborated by <jats:sup>9<\/jats:sup>Be and <jats:sup>31<\/jats:sup>P solid\u2010state nuclear magnetic resonance (NMR) spectroscopy. We present <jats:sup>9<\/jats:sup>Be NMR data for tetrahedral nitride coordination for the first time. Infrared and energy\u2010dispersive X\u2010ray spectroscopy (FTIR and EDX), as well as temperature dependent PXRD complement the analytical characterization. Density functional theory (DFT) calculations reveal super\u2010incompressible behavior and the remarkable hardness of this low\u2010density material. The formation of Be<jats:sub>2<\/jats:sub>PN<jats:sub>3<\/jats:sub> through a high\u2010pressure high\u2010temperature approach expands the synthetic access to Be\u2010containing compounds and may open access to various multinary beryllium nitrides.<\/jats:p>","DOI":"10.1002\/anie.202404953","type":"journal-article","created":{"date-parts":[[2024,4,26]],"date-time":"2024-04-26T10:28:49Z","timestamp":1714127329000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Highly Condensed and Super\u2010Incompressible Be<sub>2<\/sub>PN<sub>3<\/sub>"],"prefix":"10.1002","volume":"63","author":[{"given":"Georg","family":"Krach","sequence":"first","affiliation":[{"name":"Department of Chemistry University of Munich (LMU)  Butenandtstra\u00dfe 5\u201313 81377 Munich Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jennifer","family":"Steinadler","sequence":"additional","affiliation":[{"name":"Department of Chemistry University of Munich (LMU)  Butenandtstra\u00dfe 5\u201313 81377 Munich Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kristian","family":"Witthaut","sequence":"additional","affiliation":[{"name":"Department of Chemistry University of Munich (LMU)  Butenandtstra\u00dfe 5\u201313 81377 Munich 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 81377 Munich Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2024,6,7]]},"reference":[{"key":"e_1_2_2_1_1","doi-asserted-by":"publisher","DOI":"10.1002\/zaac.19603040313"},{"key":"e_1_2_2_2_1","doi-asserted-by":"publisher","DOI":"10.1002\/anie.200352796"},{"key":"e_1_2_2_3_1","doi-asserted-by":"publisher","DOI":"10.1002\/chem.201801951"},{"key":"e_1_2_2_4_1","doi-asserted-by":"publisher","DOI":"10.1107\/S0567739476001551"},{"key":"e_1_2_2_5_1","doi-asserted-by":"publisher","DOI":"10.1524\/zkri.1926.63.1.122"},{"key":"e_1_2_2_6_1","doi-asserted-by":"publisher","DOI":"10.1063\/1.1657557"},{"key":"e_1_2_2_7_1","doi-asserted-by":"publisher","DOI":"10.1098\/rspa.1927.0013"},{"key":"e_1_2_2_8_1","doi-asserted-by":"publisher","DOI":"10.1002\/chem.201000153"},{"key":"e_1_2_2_9_1","doi-asserted-by":"publisher","DOI":"10.1002\/anie.201910998"},{"key":"e_1_2_2_10_1","doi-asserted-by":"publisher","DOI":"10.1002\/ejic.201600042"},{"key":"e_1_2_2_11_1","doi-asserted-by":"publisher","DOI":"10.1002\/chem.201500047"},{"key":"e_1_2_2_12_1","doi-asserted-by":"publisher","DOI":"10.1021\/acs.inorgchem.3c04433"},{"key":"e_1_2_2_13_1","doi-asserted-by":"publisher","DOI":"10.1002\/chem.201700979"},{"key":"e_1_2_2_14_1","doi-asserted-by":"publisher","DOI":"10.1002\/anie.202008570"},{"key":"e_1_2_2_15_1","doi-asserted-by":"publisher","DOI":"10.1088\/1361-648X\/ab8f8a"},{"key":"e_1_2_2_16_1","doi-asserted-by":"publisher","DOI":"10.1107\/S0365110X56000693"},{"key":"e_1_2_2_17_1","doi-asserted-by":"publisher","DOI":"10.1002\/zaac.19976230112"},{"key":"e_1_2_2_18_1","doi-asserted-by":"publisher","DOI":"10.6028\/jres.073A.036"},{"key":"e_1_2_2_19_1","doi-asserted-by":"publisher","DOI":"10.1002\/cber.190704002184"},{"key":"e_1_2_2_20_1","doi-asserted-by":"publisher","DOI":"10.1002\/zaac.19261520107"},{"key":"e_1_2_2_21_1","first-page":"502","volume":"9","author":"Wiberg E.","year":"1954","journal-title":"Z.
