摘要

A porous Zn(II)-coordination polymer, namely {[Zn-2(mu(8)-abtc)(betib)]center dot DMF}(n) (1), was solvothermally synthesized from 3,3',5,5'-azobenzenetetracarboxylate (abtc(4-)) and 1,4-bis(2-ethylimidazol-1-yl)butane (betib) ligands and {[Zn-2(mu(8)-abtc)(betib)]center dot H2O}(n) (2) was obtained through the immersion of 1 in methanol. Compounds 1 and 2 were structurally characterized via numerous techniques. Both compounds displayed a 3D porous framework with a 3,6-connected sqc5381 net. Compound 2a obtained at 140 degrees C from 2 exhibited gas and iodine adsorption properties. Interestingly, the compound adsorbed selectively CO2 with the uptake capacity of 54.02 cm(3) g(-1) (13.26%) over N-2 (5.43 cm(3) g(-1)) and CH4 (14.53 cm(3) g(-1)) at 273 K. The compound also adsorbed iodine with the weights of 19.99% and 30.26% in solution and vapor phases, respectively. The single crystal X-ray result and Raman spectra showed the presence of iodine units in the pores of the framework.
