通过溶剂热法合成了两个稀土簇合物,其组成分别为:[Dy8(bpt)8(μ4-O)2(μ-OMe)8(μ1,1,3,3-N3)(μ1,3-N3)(N3)2]11H2O 9MeOH(1)和[Dy10(bpt)6(μ4-O)4(μ3-OMe)4(μ-OMe)8(μ-OAc)2(OAc)2]40H2O(2)(Hbpt=3,5-双(2-吡啶基)-1,2,4-三氮唑).1的簇核结构由两个[Dy4(μ4-O)]四面体通过罕见的μ1,1,3,3和μ1,3叠氮桥连接而成,2则由四个共边连接的[Dy4(μ4-O)]四面体组成.两个簇合物都表现出单分子磁体行为,其中2是核数最高的纯稀土单分子磁体.
Two rare earth cluster compounds were synthesized by the solvothermal method. The composition of the rare earth cluster was as follows: [Dy8 (bpt) 8 (μ4-O) 2 (μ-OMe) 8 (μ1,1,3,3-N3) 3-N3) (N3) 2] 11H2O 9MeOH (1) and [Dy10 (bpt) 6 (μ4-O) 4 (μ3- OMe) 4 (μ-OMe) 8 (μ-OAc) 2 (OAc) 2] 40H2O (2) (Hbpt = 3,5-bis (2-pyridyl) -1,2,4-triazole). The cluster structure of 1 consists of two [Dy4 (μ4-O) Of μ1, 1, 3, 3 and μ1,3 azide bridges, and 2 consists of four [Dy4 (μ4-O)] tetrahedra linked together.All the two clusters show single molecules Magnet behavior, where 2 is the highest number of pure rare earth single-molecule magnets.
