摘要:以Sm(NO*6H1O、Dy(NO):6H1O、吡啶-2、5-二焌酸( dpdc)为原料,用水热合成法合成了2个新的稀土金属配合物
n(pyde)a(H0)-4H1O(Ln=Sm(1),Dy(2),単晶结构经X单晶衍射仪分析确定,两种配合物的晶系均为单斜晶系C2l空间群
对晶体的性质进行元素分析、热重、红外光谱,荧光等分析。结果表明,配合物1和2在常温下表现出稀土离子相应的特征荧光
发射。另外,本文对两种配合物进行了热稳定性及动力学分析。

Abstract: "Two new Lanthanide complexes [In(pydc
rothennal reactions of Ln(NO: )3 6H 0, pyridine-2. 5-dicarboxylic acid(Hapydc)with 1: 1 mole ratio. Single
crystal X-ray difraction analysis reveals that both the crystals belong to monoclinic, space group C2/. The
structure and property of complexes have been characterized by elemental analysis, thermal analyses, IR spectra
and Fluorescence. The single crystal structures show that the two complexes are isomorphic and have zero
dimensional structures and hydrogen bonds result in three-dimensiona
supramolecular structures. the
coordination number of central ion In(ldis nine. The complex 1 and 2 exhibit intense luminescence in the liquid
state at room temperature. CCDC: 869044, 1; 874032, 2.

At present, because of their unique properties in selection of metal and ligand will have greatly affected
physical and chemical, Rare earth coordination to their structure and properties. In the choice o
polymers have shown a wide application prospect in metal, we found that the rare earth elements
magnetic, catalysis, fluorescence
adsorpdon and
ld contribute to the synthesis of novel coordination
separation application, etc Therefore, in the process polymers. In the choice of ligand, because of [lexible
of the design and synthesis of these complexes, the coordination mode and strong coordination ability
