Abstract: A new hybrid compound based on porous metal–organic frameworks and polyoxometalates H4[(Cu4Cl)3(BTC)8]2[SiW12O40]·(C4H12N)6·3H2O (NENU-15, BTC=1, 3, 5-benzenetricarboxylate) has been hydrothermally synthesized and its crystal structure, stability and porosity have been characterized. The experimental results showed that the introduction of polyoxometalates improved the integral stability of the compound. In addition, NENU-15 was employed in NO removal for the first time. By virtue of the synergistic effect between host frameworks and guest polyoxometalates, it not only displayed good adsorption behavior for NO, but also exhibited superior activity in NO decomposition.

Abstract: Under hydrothermal conditions using a triazole derivative ligand 3-carboxylic acid-4H-1,2,4-triazole (HL) and corresponding lead(II) salts, a novel two-dimensional(2D) lead(II) complex {[Pb(L)(μ2-Cl)(H2O)} n (1) has been isolated. In 1 Pb2Cl2(H2O)2 building blocks can be observed, which are extended by tetra-dentate coordinated L ligands to form a 2D corrugated layered structure. 1 also represents a novel example of luminescent lead(II) frameworks with triazole derivatives. Solid-state fluorescence spectrum of 1 exhibits the excited peak at 376nm while the emission peak at 604nm. [Copyright &y& Elsevier]
