Two new ZnII–LnIII heterometallic complexes derived from the amine-phenol ligand, namely [Zn2Ln(L)2(H2O)2](ClO4)3·3.5H2O (Ln = Dy (1) and Tb (2), H2L = 1,2-bis(3-methoxysalicylideneethylaminooxy)ethane), have been synthesized and structurally characterized. Complexes 1 and 2 are isomorphic trinuclear clusters and crystallize in the triclinic P![[1 with combining macron]](https://www.rsc.org/images/entities/char_0031_0304.gif)
space group. Magnetic measurements indicate that complex 1 exhibits field-induced slow magnetic relaxation with energy barrier of 27.91 K. Both display strong fluorescence emissions, which are typical narrow emission bands of lanthanide ions. Moreover, complex 2 shows a proton conductivity of 6.43 × 10−5 S cm−1 at 60 °C and 98% relative humidity. Complexes 1 and 2 as multifunctional materials may offer a potential application in magnetic, luminescent, and electrical devices.

基于胺-酚配体的多功能ZnII–LnIII（Ln = Tb，Dy）配合物，具有场诱导的慢磁弛豫，发光和质子传导
由胺-酚配体衍生的两种新的Zn II -Ln III杂金属配合物，即[Zn 2 Ln（L）2（H 2 O）2 ]（ClO 4）3 ·3.5H 2 O（Ln = Dy（1）和Tb（2），H 2 L ＝ 1，2-双（3-甲氧基水杨基亚乙基氨基氧基）乙烷）已经合成并在结构上表征。配合物1和2是同构三核簇，在三斜晶P空间群中结晶。磁测量表明复合物1表现出场致的慢磁弛豫和27.91 K的能垒。两者均显示出强荧光发射，这是镧系元素离子的典型窄发射带。此外，配合物2在60℃和98％相对湿度下显示出6.43×10 -5 S cm -1的质子传导率。配合物1和2作为多功能材料可以在磁性，发光和电气设备中提供潜在的应用。
