In this paper, bis-monodentate Schiff base ligand (2,4-Cl-ba)2bn and its 1D copper(I) coordination polymer [Cu2(μ-(2,4-Cl-ba)2bn)(μ-I2)]n are synthesized and characterized by the elemental analysis (CHN), FT-IR and 1H NMR spectroscopy. Their crystal structure is determined from the single crystal X-ray diffraction analysis. The thermal behavior of the complex is studied using thermogravimetry in order to evaluate its thermal stability and thermal decomposition pathway. The X-ray results show that the free Schiff base ligand (2,4-Cl-ba)2bn is centrosymmetric and coordinated to copper(I) ions via two iminic nitrogen atoms as a bis-monodentate bridging ligand. The coordination geometry around the copper ions is a distorted triangle formed by one nitrogen and two iodine atoms. The distance between the two symmetry-related copper atoms is very short: 2.4756(8) A.

具有柔性席夫碱配体的一维铜 (I) 配位聚合物 [Cu2(µ-(2,4-Cl-ba)2bn)(µ-I2)]n：合成、晶体结构和热稳定性

在本文中，双单齿席夫碱配体 (2,4-Cl-ba)2bn 及其一维铜 (I) 配位聚合物 [Cu2(μ-(2,4-Cl-ba)2bn)(μ-I2) ]n 合成并通过元素分析 (CHN)、FT-IR 和 1H NMR 光谱表征。它们的晶体结构由单晶 X 射线衍射分析确定。使用热重法研究复合物的热行为，以评估其热稳定性和热分解途径。X 射线结果表明，自由席夫碱配体 (2,4-Cl-ba)2bn 是中心对称的，并通过两个亚胺氮原子与铜 (I) 离子配位作为双单齿桥接配体。铜离子周围的配位几何形状是一个由一个氮原子和两个碘原子形成的扭曲三角形。两个对称相关的铜原子之间的距离非常短：2。
