Statistical Distribution of Binary Ligands within Rhodium–Organic Octahedra Tunes Microporosity in Their Assemblies

Structure–porosity relationships for metal–organic polyhedra (MOPs) are hardly investigated because they tend to be amorphized after activation, which inhibits crystallographic characterization. Here, we show a mixed-ligand strategy to statistically distribute two distinct carbazole-type ligands within rhodium-based octahedral MOPs, leading to systematic tuning of the microporosity in the resulting amorphous solids.
