摘要: 在水热反应条件下成功地合成了3个4d-4f异金属化合物{[LnAg2(QA)4(H2O)5](ClO4)}n(Ln=Nd(1),Tb(2),Eu(3);HQA=3-喹啉羧酸)。用单晶衍射分析,元素分析和粉末衍射分析对晶体结构进行了表征。化合物1~3同构,在bc平面形成二维层结构,抗衡离子ClO4-与二维层通过氢键作用形成三维超分子结构。研究了配合物2和3的荧光性质。 |

Abstract: Three 4d-4f heterometallic coordination compounds, namely, {[LnAg2(QA)4(H2O)5](ClO4)}n(Ln=Nd(1), Tb(2), Eu(3); HQA=3-quinolinecarboxylate acid), were successfully synthesized under hydrothermal conditions.Compounds 1~3 are isostructural and feature 2D layer structures on bc plane, which are further connected by the counter anions ClO4- by hydrogen bonds into 3D supermolecular structure.All these compounds are characterized by single-crystal X-ray diffraction, elemental analyses(EA) and powder X-ray diffraction(PXRD).Furthermore, the thermal stabilities and fluorescent properties of the selected compounds have been investigated.CCDC:1038767, 1; 1039837, 2; 1038768, 3. |
