摘要 用超声波辅助的方法合成得到了一个双核β-二酮镝配合物Dy2(Hpdm)2(dbm)4·2EtOH(1)(H2pdm=2,6-吡啶二甲醇,Hdbm=二苯甲酰甲烷)。单晶X-射线衍射结构分析表明双核镝(Ⅲ)结构单元通过2,6-吡啶二甲醇配体中去质子化的羟基氧原子桥联,每个镝(Ⅲ)离子呈现不规则的八面体配位构型。磁学性质研究表明,该配合物中镝(Ⅲ)离子之间存在着反铁磁性耦合作用,但没有出现磁驰豫行为。 A new dinuclear Dy (Ⅲ)β-diketonate complex, Dy2 (Hpdm)2 (dbm)4 .2EtOH (1, H2pdm =2,6- pyridinedimethanol, Hdbm =dibenzoylmethane), has been successfully prepared by ultrasonic method. Single crystal X-ray crystallographic analysis revealed that the two Dy(Ⅲ) ions are bridged by the deprotonated alkoxide arm of the pdmH-ligand. Variable-temperature magnetic susceptibility measurements showed that there exists a weak antiferromagnetic interaction between the two Dy (Ⅲ)ions, but no relaxation process of magnetion was observed, even when a 2000 Oe dc field was applied.
