By the employment of 5-amino-1H-tetrazole and pyromellitic acid ligands to assemble with Zn2+ ions, a three-dimensional3,4-connect fry network {[Zn2(HATZ)(ATZ)2(PMA)0.5]·(H2O)5}n (GUPT-1, HATZ = 5-amino-1H-tetrazole, H4PMA acid) was isolated in hydrothermal reaction, which features high stability exhibits adsorption selectivity CO2/N2 (118) under ambient conditions 1 bar. Moreover, grand canoni...
