Imparting structural robustness of metal-organic cages based on oxo-dimolybdenum clusters

A family of robust and stable molybdenum-based metal-organic cages have been obtained based on the [Mo2O2(& mu;2-O)2]2+ secondary building unit. The resulting cages are decorated with different pyrdine derivatives that impart structural stability, resulting in the structural elucidation of the activated cage with single-crystal diffraction. The chemical robustness of the cage is also demonstrated by the post-synthetic modification of the cage, which allows the exchange of the pyridine derivatives without rupture of the cage. A family of robust and stable molybdenum-based metal-organic cages have been obtained based on the [Mo2O2(& mu;2-O)2]2+ secondary building unit.

Automated summary

A family of robust and stable molybdenum-based metal-organic cages have been obtained using the [Mo2O2(& mu;2-O)2]2+ secondary building unit. The cages are decorated with different pyridine derivatives, which enhance the structural stability and allow for the determination of the activated cage's structure through single-crystal diffraction. The chemical robustness of the cage is demonstrated by the post-synthetic modification that enables the exchange of pyridine derivatives without breaking the cage structure.
