UiO-66, MOF-808 and NU-1000 metal–organic frameworks exhibit a differentiated reactivity toward [Mg­(OMe)2(MeOH)2]4 related to their pore accessibility. Microporous UiO-66 remains unchanged while mesoporous MOF-808 and hierarchical micro/mesoporous NU-1000 materials yield doped systems containing exposed MgZr5O2(OH)6 clusters in the mesoporous cavities. This modification is responsible for a remarkable enhancement of the catalytic activity toward the hydrolytic degradation of P–F and P–S bonds of toxic nerve agents, at room temperature, in unbuffered aqueous solutions.

Methanolic reduction of [PdCl2(CH3CN)2] on a [Ni(2,5-di(1H-pyrazol-4-yl)benzenesulfonate)2] metal organic framework gives rise to Pd(2+)/Pd(0) nanocomposites with Suzuki and carbonylative Suzuki heterogeneous catalytic activities.
