摘要

Two novel porous metal-organic frameworks {Zn_7(btc) _4(dmtrz)_2(H_2O)_5}_n (1) and {[Zn_6(btc)_4(dmtrz)_3]?_3H _3?_2H_2O}_n (2) (H3btc = 1,3,5-benzenetricarboxylic acid, Hdmtrz = 3,5-dimethyl-1H-1,2,4-triazole) have been solvothermally synthesized. Single-crystal structure analysis reveals that both structure 1 and 2 contain special triazole-carboxylate shared paddle-wheel units. The crucial factors to the assembly of such paddle-wheel units are discussed. Gas adsorption studies suggest that 2 is a potential microporous material for adsorptive separation of CO_2 over N_2.
