Solvothermal reactions of CuX2 (X = NO3, Cl, Br, I) with tetra-pyridyl-functionalized calix[4]arene at 130 °C afforded four novel coordination polymers, [(CuNO3)2L]·MeOH}n (1), [(CuCl2)L0.5]n (2), [(Cu3Br3)L]n (3), and [(Cu3I3)L]n (4), where L = 25,26,27,28-tetra[(3-pyridylmethyl)oxy]calix[4]arene. All the products were characterized by infrared spectroscopy, thermogravimetric analysis, single-crystal
CuX 2(X = NO 3,Cl,Br,I)与四吡啶基官能化杯[4]芳烃在130°C的溶剂热反应制得四种新型配位聚合物,[((CuNO 3)2 L]·MeOH} n(1),[(CuCl 2)L 0.5 ] n(2),[(Cu 3 Br 3)L] n(3)和[(Cu 3 I 3)L] n(4),其中L = 25,26,27,28-四[(3-吡啶基甲基)氧基]杯[4]芳烃。所有产品均通过红外光谱,热重分析,单晶X射线衍射和粉末X射线衍射进行表征。晶体结构分析表明,1拥有由单核[Cu(NO 3)]单元和L个连接基构成的一维(1D)双链,而2个具有1D链,其碗形L配体起着连接连接基的作用。双核[Cu 2 Cl 4 ]单元。化合物3和4具有相似的二维网络,其中每个三核[Cu 3 Br 3 ] / [Cu 3 I3 ]单元充当三个连接节点,通过共享L个配体连接其六个等价物。这些结果表明,不同的阴离
