The -{Er} complex [ErCl()(OH)(HO)]Cl·HO ( = 9.4; H() = -vanillin) (1) was generated by an method. The isolated Er(iii) complex 1 was characterized by elemental analysis and molecular spectroscopy. The results of single crystal X-ray diffraction studies have shown that 1 is built up of trinuclear [ErCl()(OH)(HO)] complex cations, chloride anions and water solvate molecules. Within the complex cation the three Er(iii) central atoms are placed at the apexes of a triangle which are bridged by three () ligands with additional chelating functions and two μ-OH ligands. Additionally five aqua and one chlorido ligands complete the octa-coordination of the three Er(iii) atoms. AC susceptibility measurements reveal that the compound exhibits slow magnetic relaxation with two relaxation modes.
-{铒}配合物[ErCl( )(OH)(H₂O)]Cl·H₂O ( = 9.4; H( ) = -香草醛) (1) 通过一种 方法生成。分离得到的铒(iii)配合物1通过元素分析和分子光谱进行了表征。单晶X射线衍射研究结果表明，1由三核[ErCl( )(OH)(H₂O)]配合物阳离子、氯离子阴离子和水溶剂化分子组成。在配合物阳离子中，三个铒(iii)中心原子位于三角形的顶点，由三个具有额外螯合功能的( )配体和两个μ-OH配体桥连。此外，五个水合配体和一个氯配体完成了三个铒(iii)原子的八配位。交流磁化率测量表明，该化合物表现出具有两种弛豫模式的慢磁弛豫。 （注：原文中部分括号内容缺失具体信息）
