5-（1H-四唑-1-基）烟酸（H（2）L）与Cu（II）离子反应生成一个新的金属有机骨架{[CuL]·DMF·H（2）O}（∞）（1）（DMF = N，N-二甲基甲酰胺），具有金红石型网状拓扑结构.化合物1具有带有1D通道的3D结构，可以去溶剂化以产生微孔材料。研究了脱溶剂固体[CuL]（1a）对N（2）、H（2）、O（2）、CO（2）和CH（4）等气体的吸附性能，结果表明，[CuL]（1a）对N（2）、H（2）、O（2）和CO（2）等气体具有较好的吸附性能，在77 K时对O（2）和H（2）具有高选择性比，在195、273和298 K时对CO（2）和CH（4）具有高选择性比。此外，1a在77 K下具有优异的O（2）吸收性能，在室温（298 K）和常压下对CO（2）具有显著的高吸附量，表明其在气体分离或净化方面具有潜在的应用前景。
5-(1H-Tetrazol-1-yl)isophthalic acid (H(2)L) reacts with Cu(II) ion forming a new metal-organic framework {[CuL]·DMF·H(2)O}(∞) (1) (DMF = N,N-dimethylformamide), with a rutile-related type net topology. Compound 1 possesses a 3D structure with 1D channels that can be desolvated to yield a microporous material. Adsorption properties (N(2), H(2), O(2), CO(2), and CH(4)) of the desolvated solid [CuL] (1a) have been studied, and the results exhibit that 1a possesses fairly good capability of gas sorption for N(2), H(2), O(2), and CO(2) gases, with high selectivity ratios for O(2) over H(2) at 77 K and CO(2) over CH(4) at 195, 273, and 298 K. Furthermore, 1a has excellent O(2) uptake at 77 K and a remarkably high quantity of adsorption for CO(2) at room temperature (298 K) and atmospheric pressure, suggesting its potential applications in gas separation or purification.
