[Cu(CPA)(BDC)] (CPA = 4-(Chloro-phenyl)-pyridin-4-ylmethylene-amine; BDC = 1,4-benzenedicarboxylate) has been synthesized and structurally characterized by single crystal X-Ray diffraction measurement. The structural studies establish the copper (II) containing 2D sheet with (4,4) square grid structure. The square grid lengths are 10.775 and 10.769 Å. Thermal stability is assessed by TGA, and subsequent PXRD data establish the crystallinity. The surface morphology is evaluated by FE-SEM. The N adsorption-desorption analysis demonstrates the mesoporous feature (∼6.95 nm) of the Cu-MOF. This porous grid serves as heterogeneous green catalyst with superficial recyclability and thermal stability and facilitates organic transformations efficiently such as, Click and Knoevenagel reactions in the aqueous methanolic medium.
[Cu(CPA)(BDC)]（CPA=4-（氯苯基）-吡啶-4-亚甲基胺；BDC=1,4-苯二甲酸二甲酯）已通过单晶 X 射线衍射测量法进行合成和结构表征。结构研究确定了含有 2D 片层的铜（II），具有（4,4）正方形网格结构。正方形网格长度分别为 10.775 和 10.769 Å。通过 TGA 评估热稳定性，并通过后续 PXRD 数据确定结晶度。通过 FE-SEM 评估表面形态。N 吸附-解吸分析表明 Cu-MOF 具有介孔特征（约 6.95nm）。这种多孔网格可用作具有表面可回收性和热稳定性的异相绿色催化剂，并能有效地促进有机转化，如在甲醇水相中进行点击反应和 Knoevenagel 反应。
