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 of the difficulty in structural characterization. Here, we show a mixed ligand strategy to statistically distribute two distinct carbazole-type ligands within rhodium-based octahedral MOPs, leading to systematical tuning of the microporosity in the resulting amorphous solids.
