The development of electron microscopy has made it possible to observe directly the zeolitic framework and the distribution of extra framework cations within the pores at the atomic level. Here, we have studied the EMT framework providing data with an unprecedented spatial resolution, which have allowed the analysis of the FAU domains present in the framework. Additionally, potassium and lead (introduced by aqueous ion exchange), which were nonperiodically distributed in the pores have been located. An alternative image mode, annular bright field, has been used, proving its usefulness to extend the spatial resolution and increase the sensitivity toward light elements such as bridging oxygen. Finally, the combination of atomic imaging (local information) with the three-dimensional electron diffraction tomography analysis (averaged information) determined the lead-EMT crystal symmetry to be P63mc. 000111647 536__ $$9info:eu-repo/grantAgreement/ES/MICINN/RYC-2018-024561-I$$9This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 823717-ESTEEM3$$9info:eu-repo/grantAgreement/EC/H2020/823717/EU/Enabling Science and Technology through European Electron Microscopy/ESTEEM3$$9info:eu-repo/grantAgreement/ES/DGA/E13-20R 000111647 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttp://creativecommons.org/licenses/by/3.0/es/ 000111647 590__ $$a4.177$$b2021 000111647 592__ $$a1.103$$b2021 000111647 594__ $$a7.0$$b2021 000111647 591__ $$aCHEMISTRY, PHYSICAL$$b78 / 165 = 0.473$$c2021$$dQ2$$eT2 000111647 593__ $$aElectronic, Optical and Magnetic Materials$$c2021$$dQ1 000111647 591__ $$aMATERIALS SCIENCE, MULTIDISCIPLINARY$$b143 / 345 = 0.414$$c2021$$dQ2$$eT2 000111647 593__ $$aSurfaces, Coatings and Films$$c2021$$dQ1 000111647 591__ $$aNANOSCIENCE & NANOTECHNOLOGY$$b62 / 109 = 0.569$$c2021$$dQ3$$eT2 000111647 593__ $$aPhysical and Theoretical Chemistry$$c2021$$dQ1 000111647 593__ $$aEnergy (miscellaneous)$$c2021$$dQ1 000111647 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000111647 700__ $$aSmith, D. 000111647 700__ $$aReadman, J.
