A series of new lanthanide azelates [Ln(aze)(Haze)(H₂O)]·H₂O {Ln = La (1a), Ce (1b), Pr (1c); H₂aze = azelaic acid}, [Ln₂(aze)₃(phen)₂]·H₂O [Ln = Nd (2a), Er (2b); phen = 1,10-phenanthroline], [Sm(aze)(Haze)(phen)]·2H₂O (3), [Gd(aze)(phen)₂]·ClO₄ (4) and (Hphen)[Tb₂(aze)₂(phen)₄]·3ClO₄ (5) were hydrothermally prepared and structurally characterized.1a-c are isostructural and show 3-D framework based on 1-D infinite [Ln-O-Ln]_n chain. 2a-b exhibit sql layer, while 3 displays 1-D chain, where phen ligands locate at both sides of the chain. The Ln³⁺ ions of 4 and 5 are connected by aze²⁻ into two different types of rare cationic 1-D chains. The luminescent investigations show that both 2a and 2b exhibit interesting NIR luminescence and 5 displays a good potentiality as a luminescent sensor targeted for Fe³⁺ ion. Of particular interest, lanthanide azelates have not been to date documented, while this work presents the only examples of lanthanide azelates exhibiting luminescent properties. The magnetic properties of some lanthanide azelates were also investigated.

一系列新的镧系元素壬二酸酯[Ln（aze）（Haze）（H ₂ O）]·H ₂ O {Ln = La（1a），Ce（1b），Pr（1c）; H ₂ aze ＝壬二酸}，[Ln ₂（aze）₃（phen）₂ ]·H ₂ O [Ln = Nd（2a），Er（2b）；phen = 1,10-菲咯啉]，[Sm（aze）（Haze）（phen）]·2H ₂ O（3），[Gd（aze）（phen）₂ ]·ClO ₄（4）和（Hphen）[ Tb ₂（aze）₂（phen）₄ ]·3ClO ₄（5）被水热制备并在结构上表征。图1a-c是同构的，并且示出了基于一维无限[Ln-O-Ln] _n链的3-D框架。2a-b显示sql层，而3显示1-D链，其中phen配体位于链的两侧。Ln的³⁺的离子4和5通过连接AZE ^2-入两种不同类型的稀有阳离子1- d链。发光研究表明2a和2b均表现出有趣的NIR发光，而5则作为针对Fe ³⁺的发光传感器具有良好的潜力。离子。特别令人感兴趣的是，迄今为止尚未记录镧系元素壬二酸酯，而这项工作是呈现出发光性能的镧系元素壬二酸酯的唯一实例。还研究了一些镧系元素壬二酸盐的磁性。
