以芳香羧酸配体构筑的Co(Ⅱ)配位聚合物的合成及结构

Synthesis and Structure Analysis of Single Crystal of Transition Metal Co

选用1,4-二(3,5-二羧基吡唑-1-甲基)苯作为配体,Co^(2+)作为中心离子,在水热条件下合成了一例Co(Ⅱ)配位聚合物Co(1,4-bdyb)_2(H_2O)_2(1,4-bdyb=1,4-二(3,5-二羧基吡唑-1-甲基)苯),并通过X-射线单晶衍射、X-射线粉末衍射、红外光谱和热重分析对其进行了详细表征,最终确定了该配合物中心离子Co(Ⅱ)采取六配位模式,与配体交替连接形成一维链结构。

1,4-bis(3,5-dicarboxypyrazole-1-methyl)benzene was used as the ligand,Co2+was used as the central ion,Co(II)coordination polymer was synthesized under hydrothermal condition.It was characterized by X-ray single crystal diffraction,X-ray powder diffraction,infrared spectroscopy and thermogravimetric analysis,it was finally determined that the central ion Co(II)of the complex adopts a six-coordination mode and alternates with the ligand,the connections form a one-dimensional chain structure.
