Adsorption of Iodine Based on a Tetrazolate Framework with Microporous Cages and Mesoporous Cages

A three-dimensional tetrazolate framework was synthesized with solvothermal reaction. Single-crystal X-ray diffraction analysis shows that the framework is fabricated by a microporous cage (1.35 nm) and mesoporous cage (2.85 nm) via vertex-sharing packing mode. This compound shows permanent porosity and excellent performance of absorbing iodine.
