A novel water stable porous metal–organic framework (MOF), [Cu₃(OH)₂(IBA)₂(CH₃COO)₂]·DMA (1) (HIBA = 4-(imidazol-1-yl)-benzoic acid, DMA = N,N-dimethylacetamide), has been solvothermally synthesized and structurally characterized. The framework of compound 1 is constructed from rod SBUs with a new (5,8)-connected topology. Compound 1 exhibits exceptional chemical stability under various conditions (organic solvents, water, boiling water or pH = 1–8 acidic and basic aqueous solutions). Meanwhile, it exhibits good selectivity for CO₂ over CH₄ (6.6 for CO₂/CH₄ = 0.5/0.5 and 5.8 for CO₂/CH₄ = 0.05/0.95 under 1 bar at 298 K). The excellent stability of compound 1 is of extreme importance for its practical industrial applications.

基于棒状SBU的水稳定性微孔金属-有机骨架：合成，结构和吸附性能†

一种新型的水稳定性多孔金属-有机骨架（MOF），[Cu ₃（OH）₂（IBA）₂（CH ₃ COO）₂ ]·DMA（1）（HIBA = 4-（咪唑-1-基）-苯甲酸溶剂热合成并在结构上表征了丙烯酸（DMA ＝N，N-二甲基乙酰胺）。化合物1的框架由具有新的（5,8）连接拓扑的棒状SBU构成。化合物1在各种条件下（有机溶剂，水，沸水或pH = 1-8的酸性和碱性水溶液）显示出出色的化学稳定性。同时，它对CH ₂表现出比CH ₄更好的选择性（在1 bar和298 K下，对于CO ₂ / CH _4的6.6为0.5 / 0.5，对于CO ₂ / CH _4的5.8为0.05 / 0.95）。化合物1的优异稳定性对其实际工业应用至关重要。
