摘要/Abstract

摘要： 镉配合物因其独特的结构及性质而被广泛应用于光学、医药、化学等领域,水热法因其溶剂清洁、操作简单等因素是目前合成配合物方便有效的方法之一。本文以2,6-双(2-吡嗪基)-4,4′-联吡啶(L)、对苯二甲酸和CdCl₂·2.5H₂O为原料,运用水热合成法合成了配位化合物[Cd₂(L)₂(bdc)(H₂O)₄](bdc),用X射线单晶衍射技术、红外光谱分析等手段对所合成配合物进行了结构和发光性质的表征。研究发现:配合物[Cd₂(L)₂(bdc)(H₂O)₄](bdc)属于三斜晶系,P1空间群,晶胞参数为a=1.002 78(17) nm,b=1.044 25(17) nm,c=1.274 8(2) nm,β=78.559(2)°,且具有良好的荧光性能。

Abstract: Cadmium complexes are widely used in the fields of optics, medicine, chemistry and so on because of their unique structure and properties.Hydrothermal method is one of the most convenient and effective methods to synthesize complex at present because of its solvent cleaning and simple operation. A compound [Cd₂(L)₂(bdc)(H₂O)₄](bdc) was hydrothermally synthesized using 2,6-di(pyrazin-2-yl)-4,4′-bipyridine(L), terephthalic acid and CdCl₂·2.5H₂O as raw materials, the structure and luminescent properties of the complexes were characterized by single crystal X-ray diffraction and infrared spectroscopy. The experimental results show that the [Cd₂(L)₂(bdc)(H₂O)₄](bdc) belongs to the triclinic system, P1 space group, a=1.002 78(17) nm, b=1.044 25(17) nm, c=1.274 8(2) nm, β=78.559(2)°, and has good fluorescence.
