Two novel porous metal鈥搊rganic frameworks {Zn₇(btc)₄(dmtrz)₂(H₂O)₅}_n (1) and {[Zn₆(btc)₄(dmtrz)₃]路3H₃O路2H₂O}_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 CO₂ over N₂.
