| 摘要: 本文利用柔性配体双三唑甲烷(btm),在水热条件下合成了2个新的配合物[Cu0.5(btm)Cl]n (1)和[Cu(btm)Cl2]n (2)。实验表明,氯离子的配位模式会随着金属和配体的比例的不同而改变,从而得到了两种结构不同的配合物。化合物1为一维链状结构,链与链之间通过四重Cl…H-C氢键组合成了三维超分子结构。化合物2为二维(4.4)连接的网状结构,单重氢键Cl…H-C将二维层连接为三维结构。两种配合物用单晶X-衍射、元素分析、热重、顺磁共振等技术进行了表征。 |

| Abstract: Using a flexible bis-triazole ligand bis(1,2,4-triazol-1-y1)metane (btm), two new copper(Ⅱ) coordination polymers [Cu0.5(btm)Cl]n (1) and [Cu(btm)Cl2]n (2) have been synthesized under hydrothermal conditions. The coordinating mode of chlorine anions can be tuned as a result of changing the metal/ligand ratio in the reaction system, which ultimately forms two novel structures. 1 possesses infinite 1D chain structure, and uncommonly four-fold Cl…H-C hydrogen bonds help the chains form a 3D supramolecular architecture. 2 features 2D (4.4) net framewok. Hydrogen bonds (Cl…H-C) reside among the 2D layers, which link the 2D layers to lead to a 3D supramolecular architecture. For 1 and 2, X-ray crystallography, elemental analysis, thermal stability and EPR spectra have been carried out. CCDC: 932333, 1; 932332, 2. |
