摘要:研究以巴比妥酸与过渡金属 Cd、Co、Cu 形成配合物的结构特征及荧光性能。在常温
条件下通过溶液法由配体与过渡金属盐自组装,合成了三个配合物[CdL2(H2O)2]n (1)、
[CoL2(H2O)4] (2)、[CuL2(H2O)3] (3)(L=barbituric acid)。用 X-射线单晶衍射测定其晶体结
构表明,配合物 1 为斜方晶系,Ibam 空间群,配合物 2 为单斜晶系,C2/c 空间群,配合物
3 为斜方晶系,Fdd2 空间群。通过 FL(固体荧光光谱分析)对配合物 1 进行表征,配合物 1
荧光发射很强,是一种潜在的荧光材料。

Abstract: To study the structural characteristic of transition plexes based on barbituric acid
ligands, plexes [CdL2(H2O)2]n (1), [CoL2(H2O)4] (2), [CuL2(H2O)3] (3)(L=barbituric
acid) were synthesized by self-assemble of transition metals with barbituric acid ligand under
hydrothermal conditions. Their crystal structures were determined by X-ray single crystal diffraction.
Complex 1 is orthorhombic, Ibam space group, complex 2 is Monoclinic, C2/c space group, complex 3
is orthorhombic, Fdd2 space group. The luminescent property plex 1 was also determined.
Complex 1 emits strong intensity, which can be used as a potential luminescent material.
Key words: transition metal; barbituric acid; complex; crystal structure; luminescent property
