This novel methodology circumvents the use of free NHC molecules. The silver(III) carbene complexes thus prepared are unprecedented and show remarkable thermal stabilities. They display square-planar or square-pyramidal geometry. Following our calculations, the electronic structure of a model representative complex exhibits Inverse Ligand Field (ILF). The compounds reported herein are synthetic analogues of the elusive difluorocarbene and carbonyl species proposed as intermediates in the acidic decomposition of [Ag(CF3)4]−. The synthetic procedure reported is envisaged to enable access to carbene complexes of other late transition-metals in high oxidation states. 000132793 536__ $$9info:eu-repo/grantAgreement/ES/DGA/E17-23R$$9info:eu-repo/grantAgreement/ES/MICINN/PID2021-122869NB-I00$$9info:eu-repo/grantAgreement/ES/MINECO/BES-2016-078732 000132793 540__ $$9info:eu-repo/semantics/openAccess$$aby-nc-nd$$uhttp://creativecommons.org/licenses/by-nc-nd/3.0/es/ 000132793 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000132793 700__ $$0(orcid)0000-0002-0204-7713$$aJoven-Sancho, D. 000132793 700__ $$0(orcid)0000-0002-4808-574X$$aMartín, A. 000132793 700__ $$0(orcid)0000-0001-9045-5102$$aMenjón, B. 000132793 700__ $$0(orcid)0000-0002-2492-625X$$aBaya, M.$$uUniversidad de Zaragoza 000132793 7102_ $$12010$$2760$$aUniversidad de Zaragoza$$bDpto.
