摘要
用扩散法合成了一种以4,4'-偶氮联吡啶(Azpy)为第二桥联配体的新叠氮铜二维配合物[Cu(azpy)(N_3)_2]n。对配合物进行了X-射线单晶衍射结构分析、红外光谱表征及磁性性质研究。结果表明,在配合物中,铜离子之间通过EE叠氮桥联和4,4'-Azopyridine(azpy)桥联形成了一个二维层状结构,并具有4-连接(44.62)拓扑结构。对磁性数据进行分析,得出该配合物中EE-叠氮桥联的Cu(Ⅱ)离子间存在反铁磁性耦合,而配合物在低温时出现了铁磁性耦合可能是由自旋倾斜造成的弱自发磁化作用引起的。
In this work,a new 2D azido-bridged Cu complex has been synthesized with 4,4＇-azpy as the second bridged ligand by the diffusion method and characterized by X-ray crystallography,IR spectroscopy and magnetic property. The results show that the Cu（Ⅱ） ions are bridged by end-end azido ligands and 4,4＇-azpy ligands into a 2D layered structure. The magnetic data indicated the existence of antiferromagnetic interaction between the Cu （Ⅱ） ions of bridged by end-end azido, and the ferromagnetic coupling of the complex at low temperature may be due to the weak spontaneous magnetization caused by the spin canting.
