Rationally Designing Metal-Organic Frameworks Based on [Ln] Magnetic Building Blocks Utilizing 2-Hydroxyisophthalate and Fine-Tuning the Magnetic Properties of Dy Analogues by Terminal Coordinated Solvents.

By utilizing the 2-hydroxyisophthalic acid (HipO) ligand, 2D metal-organic frameworks (MOFs) featuring rare O-bridged [Ln]-magnetic building blocks (MBBs), [Ln(ipO)(DMF)(HO)] [Ln = Gd (), Dy (); DMF = ,-dimethylformamide], were rationally designed and synthesized. When the reaction solvents that behave as terminal ligands were changed, the coordination geometries of Ln ions and the arrangement fashion of [Ln]-MBBs for these MOFs were modified accordingly. Another type of 2D MOF of [Ln(ipO)(HO)]·2HO [Ln = Gd (), Dy ()] was thus obtained.
