Here, we first obtain phase-pure, colloidally stable nanocubes. Second, we elucidate the pathway by which copper(II) nitrate and oleylamine form Cu3N. We find that oleylamine is both a reductant and a nitrogen source. Oleylamine is oxidized by nitrate to a primary aldimine, which reacts further with excess oleylamine to a secondary aldimine, eliminating ammonia. Ammonia reacts with CuI to form Cu3N. Third, we investigated the surface chemistry and find a mixed ligand shell of aliphatic amines and carboxylates (formed in situ). While the carboxylates appear tightly bound, the amines are easily desorbed from the surface. Finally, we show that doping with palladium decreases the band gap and the material becomes semi-metallic. These results bring insight into the chemistry of metal nitrides and might help the development of other metal nitride nanocrystals."}],"department":[{"_id":"MaIb"}],"day":"01","type":"journal_article","file":[{"file_id":"11696","success":1,"file_size":1303202,"date_created":"2022-07-29T09:29:20Z","date_updated":"2022-07-29T09:29:20Z","content_type":"application/pdf","file_name":"2022_AngewandteChemieInternat_Parvizian.pdf","access_level":"open_access","creator":"dernst","relation":"main_file","checksum":"2a3ee0bb59e044b808ebe85cd94ac899"}],"pmid":1,"date_updated":"2023-08-03T07:19:12Z","tmp":{"image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"article_processing_charge":"No","month":"08","status":"public","related_material":{"record":[{"id":"11695","relation":"research_data","status":"public"}]},"title":"The chemistry of Cu₃N and Cu₃PdN nanocrystals","quality_controlled":"1","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","date_created":"2022-06-19T22:01:58Z","oa_version":"Published Version","oa":1,"scopus_import":"1","publisher":"Wiley","citation":{"mla":"Parvizian, Mahsa, et al. “The Chemistry of Cu₃N and Cu₃PdN Nanocrystals.” <i>Angewandte Chemie - International Edition</i>, vol. 61, no. 31, e202207013, Wiley, 2022, doi:<a href=\"https://doi.org/10.1002/anie.202207013\">10.1002/anie.202207013</a>.","ieee":"M.
