摘要
将镝的氯化物和乙二胺四乙酸二钠(EDTA)在水热条件下合成一种新的配位聚合物:[Dy(EDTA)]n,X射线单晶衍射测定表明:它是(4,4)拓扑结构的二维网层状结构,层与层之间靠O-H…O氢键弱相互作用维系成三维超分子网络结构。它的晶体数据为:正交晶系,空间群Pbcm,a=6.619 8(3),b=12.872 6(9),c=18.463 0(12),Z=8。光谱分析表明此配合物具有很强的荧光性能。
One new coordination polymers,[Dy(EDTA)]n was synthesized by hydrothermal reactions of lanthanide chlorides with EDTA,and characterized by single-crystal X-ray diffraction.It has 2-D grid-like layer structure with(4,4) topology,which is further interlinked via hydrogen bonds,resulting in a 3-D supramolecular network.Crystal data for it as representative: Orthorhombic,space group Pbcm,with a = 6.6198(3),b = 12.8726(9),c = 18.4630(12),Z = 8.The complexes exhibit strong photoluminescence of Dy(Ⅲ) for it.
