Herein, this work demonstrates the synthesis of a multi‐metallic MTV RE MOF incorporating two, four, six, or eight different RE ions with different sizes and in nearly equimolar amounts and no compositional segregation. The MOFs are formed by a combination of RE cations (La, Ce, Eu, Gd, Tb, Dy, Y, and Yb) and a 1,7‐di(4‐carboxyphenyl)‐1,7‐dicarba‐closo‐dodecaborane (mCB‐L) linker. The steric bulkiness and acidity of mCB‐L is crucial for the incorporation of different size RE ions into the MOF structure. Demonstration of the incorporation of all RE cations is performed via compositional and structural characterization. The more complex MTV MOF, including all eight RE ions (mCB‐8RE), are also characterized using optical, thermal, and magnetic techniques. Element‐selective X‐ray absorption spectroscopy and X‐ray Magnetic Circular Dichroism measurements allow us to characterize spectroscopically each of the eight RE ions and determine their magnetic moments. This work paves the way for the investigation of MTV MOFs with the possibility to combine RE ions à la carte for diverse applications. info:eu-repo/grantAgreement/ES/DGA-FSE/E12-23R-RASMIA info:eu-repo/grantAgreement/ES/MINECO/PID2019-106832RB-I00 info:eu-repo/grantAgreement/ES/MINECO/PID2021-123287OB-I00 info:eu-repo/grantAgreement/ES/MINECO/SEV-2017-0706 info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 18.5 2023 CHEMISTRY, PHYSICAL 11 / 178 = 0.062 2023 Q1 T1 MATERIALS SCIENCE, MULTIDISCIPLINARY 21 / 439 = 0.048 2023 Q1 T1 NANOSCIENCE & NANOTECHNOLOGY 9 / 141 = 0.064 2023 Q1 T1 PHYSICS, CONDENSED MATTER 5 / 79 = 0.063 2023 Q1 T1 CHEMISTRY, MULTIDISCIPLINARY 10 / 231 = 0.043 2023 Q1 T1 PHYSICS, APPLIED 9 / 179 = 0.05 2023 Q1 T1 5.496 2023 Biomaterials 2023 Q1 Electrochemistry 2023 Q1 Electronic, Optical and Magnetic Materials 2023 Q1 Nanoscience and Nanotechnology 2023 Q1 Condensed Matter Physics 2023 Q1 Materials Science (miscellaneous) 2023 Q1 Chemistry (miscellaneous) 2023 Q1 29.5 2023 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Li, Xiao-Bao Light, Mark E.
