We report here that these unusual units can be trapped within a suitable organometallic frame. Thus, the terminal auronitrene and auroxyl derivatives [(CF3)3AuN]− and [(CF3)3AuO]− were identified as local minima by calculation. These open-shell, high-energy ions were experimentally detected by tandem mass spectrometry (MS2): They respectively arise by N2 or NO2 dissociation from the corresponding precursor species [(CF3)3Au(N3)]− and [(CF3)3Au(ONO2)]− in the gas phase. Together with the known fluoride derivative [(CF3)3AuF]−, they form an interesting series of isoleptic and alloelectronic complexes of the highly acidic organogold(iii) moiety (CF3)3Au with singly charged anions X− of the most electronegative elements (X=F, O, N). Ligand-field inversion in all these [(CF3)3AuX]− species results in the localization of unpaired electrons at the N and O atoms. info:eu-repo/grantAgreement/ES/AEI/MDM-2017-0767 info:eu-repo/grantAgreement/ES/DGA/E17-20R info:eu-repo/grantAgreement/ES/MICINN/PID2021-122869NB-I00 info:eu-repo/grantAgreement/ES/MICINN/RYC-2017-22853 info:eu-repo/grantAgreement/ES/MICIU/PGC2018-093863-B-C21 info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 3.9 2023 CHEMISTRY, MULTIDISCIPLINARY 80 / 231 = 0.346 2023 Q2 T2 1.058 2023 Chemistry (miscellaneous) 2023 Q1 Organic Chemistry 2023 Q1 Catalysis 2023 Q2 7.9 2023 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Álvarez, Santiago Baya, Miguel Universidad de Zaragoza (orcid)0000-0002-2492-625X Echeverría, Jorge Universidad de Zaragoza Martín, Antonio (orcid)0000-0002-4808-574X Orduna, Jesús (orcid)0000-0003-3514-2570 Menjón, Babil (orcid)0000-0001-9045-5102 2010 760 Universidad de Zaragoza Dpto.
