Holmium-based metal-organic frameworks using the BDC linker

A series of Holmium-benzene-dicarboxylate MOFs were synthesized and characterized. Metallic dinuclear clusters were observed as a repeating motif in these and similar structures and its origin is reviewed. Furthermore, the stability of the MOFs was analyzed and their potential of these materials as radionuclide agents for cancer therapy was discussed. [Display omitted] Four different holmium-based metal-organic frameworks (MOFs) were synthesized and their structures solved by single crystal X-ray diffraction. The origin of dimeric clusters in the structure, commonly observed in lanthanide-based MOFs, is proposed and discussed. Additional characterization is presented to understand the stability of these materials. The structural features including the dimeric holmium clusters in all the MOFs is discussed and it opens the possibility to design more holmium-based MOFs.
