Novel heteroleptic anilate-based lanthanide MOFs (Ln^III = Tb, Dy, Ho) have been obtained under hydrothermal conditions by the ancillary ligand synthetic strategy. These structurally isomorphous species contain octacoordinated Ln^III ions with coordination polyhedra approaching an ideal D_2d symmetry, best described by a distorted biaugmented trigonal prismatic C_2v geometry. In the whole series, only the Dy-MOF exhibits SMM behaviour.

基于杂配苯甲酸盐的 DyIII 金属有机骨架中的慢磁弛豫

通过辅助配体合成策略，在水热条件下获得了新型杂配苯甲酸酯基镧系元素 MOF（Ln ^III = Tb、Dy、Ho）。这些结构同晶物质含有八配位的 Ln ^III离子，其配位多面体接近理想的D _2d对称性，最好用扭曲的偏增三角棱柱C _2v几何结构来描述。在整个系列中，只有 Dy-MOF 表现出 SMM 行为。
