Abstract

By employing semi-flexible multi-N donor auxiliary ligands, namely 1,4-bis(5-pyrimidyl)benzene (bpmb) in conjunction with azide, novel Co(II) 2D coordination polymers have been successfully synthesized and structurally characterized, along with magnetic analysis. The resulting compound, {Co(N3)(bpmb)(H2O)2·H2O}n (1), exhibits a unique 2D structure comprised of interconnected Co(II) chains bridged by single end-to-end (EE) azide moieties. These chains are further linked by twisted trans-μ2-N,N′-bpmb auxiliary ligands, forming a grid-like network. Additionally, the layers are held together in a 3D arrangement through hydrogen bonding interactions between the coordination water and the N atom of the bpmb ligands. Importantly, magnetic investigations reveal that compound 1 displays weak ferromagnetism attributed to spin canting, with a critical temperature (Tc) of 12 K.

一种新型二维配位聚合物中的自旋弯曲和弱铁磁性--Co(II)链由一个端对端叠氮化物桥接

通过采用半柔性多 N 供体辅助配体，即 1,4-双（5-嘧啶基）苯（bpmb）和叠氮化物，成功合成了新型 Co(II) 二维配位聚合物，并对其进行了结构表征和磁性分析。由此产生的化合物{Co(N3)(bpmb)(H2O)2-H2O}n (1)呈现出独特的二维结构，由相互连接的 Co(II) 链和单个端对端 (EE) 叠氮化物桥接而成。这些链通过扭曲的反式-μ2-N,N′-bpmb 辅助配体进一步连接，形成网格状网络。此外，通过配位水和 bpmb 配体的 N 原子之间的氢键相互作用，各层以三维排列方式固定在一起。重要的是，磁性研究表明，化合物 1 显示出了归因于自旋悬臂的弱铁磁性，临界温度 (Tc) 为 12 K。
