Rigid, microporous 3D molecular frameworks derived from 3-amino-1,2,4-triazole

The 3-amino-1,2,4-triazole (AmTAZ) ligand is a promising molecular species for formation of robust porous coordination polymers. We have recently crystallized two unusual cubic cage structures which possess μ ₂-O ^2- and μ _-3S ^2- bridges, respectively. Although nitrate anions occupy the pore in these two cationic frameworks, we anticipate that similar materials with open pores can be formed by the incorporation of the charge-compensating anion into the framework structure.
