Porous Metal–Organic Frameworks with Multiple Cages Based on Tetrazolate Ligands: Synthesis, Structures, Photoluminescence, and Gas Adsorption Properties
Three tetrazolate-based coordination polymers [MnÂ(TzA)Â(H<sub>2</sub>O)<sub>2</sub>]<sub><i>n</i></sub> (<b>1</b>, H<sub>2</sub>TzA = 1<i>H</i>-tetrazole-5-acetic acid),
{[Cd<sub>5</sub>(MTz)<sub>9</sub>]<b>·</b>OH}<sub><i>n</i></sub> (<b>2</b>, MTz = 5-methyltetrazolate), and
[Cd<sub>3</sub>(MTz)<sub>3</sub>Cl<sub>3</sub>]<sub><i>n</i></sub> (<b>3</b>) were synthesized via the reactions of a tetrazole
ligand
H<sub>2</sub>TzA with metal ions under hydrothermal conditions. During
the formation of <b>2</b> and <b>3</b>, CdÂ(II) ions were
coordinated by MTz<sup>–</sup>, which was generated as the
result of the in situ decarboxylation of the H<sub>2</sub>TzA ligand.
Single-crystal X-ray diffraction analyses revealed that <b>1</b> possessed an infinite 2D layer structure with a μ<sub>3</sub>-TzA<sup>2–</sup> moiety, forming a 4<sup>4</sup>-<b>sql</b> topology, and the 2D sheets were further hydrogen-bonded to form
a 3D framework. Compound <b>2</b> had a 3D porous framework
with a 4<sup>9</sup><sub><b>·</b></sub>6<sup>6</sup>-<b>acs</b> topology. Compound <b>3</b> adopted a 3D porous
framework with a body-centered cubic (<b>bcu</b>) topology,
which was comprised of 48-membered (Cd<sub>24</sub>Cl<sub>24</sub>) rings, and it demonstrated a moderate adsorption of H<sub>2</sub> over N<sub>2</sub> as a result of its limited window size. The solid-state
luminescent properties of complexes <b>2</b> and <b>3</b> and the corresponding HMTz molecule were also investigated
