Novel heteroleptic anilate-based lanthanide MOFs (Ln = Tb, Dy, Ho) have been obtained under hydrothermal conditions by the ancillary ligand synthetic strategy. These structurally isomorphous species contain octacoordinated Ln ions with coordination polyhedra approaching an ideal symmetry, best described by a distorted biaugmented trigonal prismatic geometry. In the whole series, only the Dy-MOF exhibits SMM behaviour.
通过辅助配体合成策略，在水热条件下获得了新型异配位苯胺基镧系金属有机框架材料（Ln = Tb、Dy、Ho）。这些结构同构的物种包含八配位的Ln离子，其配位多面体接近理想对称性，用扭曲的双增三角棱柱几何结构来描述最为合适。在整个系列中，只有Dy-MOF表现出单分子磁体行为。
