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.2023http://zaguan.unizar.es/record/12438110.1002/chem.202203181http://zaguan.unizar.es/record/124381oai:zaguan.unizar.es:124381info:eu-repo/grantAgreement/ES/AEI/MDM-2017-0767info:eu-repo/grantAgreement/ES/DGA/E17-20Rinfo:eu-repo/grantAgreement/ES/MICINN/PID2021-122869NB-I00info:eu-repo/grantAgreement/ES/MICINN/RYC-2017-22853info:eu-repo/grantAgreement/ES/MICIU/PGC2018-093863-B-C21Chemistry - A European Journal 29, 8 (2023), e202203181 [7 pp.]by-nc-ndhttp://creativecommons.org/licenses/by-nc-nd/3.0/es/info:eu-repo/semantics/openAccess
