In their reports, 2 was claimed to be obtained starting from either [AgIII(CF3)3Cl]− (3⋅Cl) or [AgIII(CF3)4]− (1) via halide abstraction using AgNO3 or acidic treatment, resp. These two synthetic routes are herein reinvestigated. The feasibility of Naumann's method is demonstrated, thus providing 2 yet accompanied by its s‐triazinyl derivative [AgIII(CF3)3(C6H9N3)] (2’). The formation of 2’ is unprecedented and was thereby investigated. Both 2 and 2’ were isolated in pure fashion and fully characterized. In turn, halide extraction from 3⋅Cl leads to the AgIII‐ONO2 anion 5 instead of 2, as evidenced by NMR spectroscopy, EA and Sc‐XRD.2024http://zaguan.unizar.es/record/13531710.1002/chem.202400881http://zaguan.unizar.es/record/135317oai:zaguan.unizar.es:135317info:eu-repo/grantAgreement/ES/DGA/E17-23Rinfo:eu-repo/grantAgreement/ES/MICINN/PID2021-122869NB-I00Chemistry - A European Journal (2024), e202400881 [8 pp.]by-nchttps://creativecommons.org/licenses/by-nc/4.0/deed.esinfo:eu-repo/semantics/openAccess
