Three new products, [Cu(dppa)(2,2'-bipy)(HO)]·2HO (), [Co(dppa)(phen)(HO)]·2HO (), and [Co(dppa)(4,4'-bipy)(HO)]·3HO () were synthesized using a hydrothermal method from Cu(II) and Co(II) metal(II) chlorides, 3-(3,4-dicarboxyphenoxy)phthalic acid (Hdppa), and different auxiliary ligands, namely 2,2'-bipyridine (2,2'-bipy),1,10-phenanthroline (phen), and 4,4'-bipyridine (4,4'-bipy). Products - were characterized by elemental analysis, FTIR, TGA, PXRD, SEM, and single-crystal X-ray crystallography. The structure of features a 1D chain of the 2C1 topological type. Compound shows a discrete tetrameric complex. Product demonstrates a 3D metal-organic framework (MOF) with the new topology. Their structure and topology, thermal stability, and catalytic activity were studied. In particular, excellent catalytic activity was demonstrated for copper(II)-polymer in the cyanosilylation reaction at 35 °C.
使用水热法，由氯化铜（II）和氯化钴（II）金属（II）盐、3-(3,4-二羧基苯氧基)邻苯二甲酸（Hdppa）以及不同的辅助配体，即2,2'-联吡啶（2,2'-bipy）、1,10-菲啰啉（phen）和4,4'-联吡啶（4,4'-bipy），合成了三种新产品，[Cu(dppa)(2,2'-bipy)(HO)]·2HO （）、[Co(dppa)(phen)(HO)]·2HO （）和[Co(dppa)(4,4'-bipy)(HO)]·3HO （）。通过元素分析、傅里叶变换红外光谱（FTIR）、热重分析（TGA）、粉末X射线衍射（PXRD）、扫描电子显微镜（SEM）和单晶X射线晶体学对产物 - 进行了表征。 的结构具有2C1拓扑类型的一维链。化合物 显示出离散的四聚体配合物。产物 展示了具有新拓扑结构的三维金属有机框架（MOF）。研究了它们的结构和拓扑、热稳定性以及催化活性。特别是，铜（II）聚合物 在35°C的氰基硅烷化反应中表现出优异的催化活性。
