Abstract

The hydrothermal reactions of Ln₂O₃, [Cu(2,2′-bpy)₂](ClO₄) and isophthalic acid (H₂ip) yielded a series of heterometallic coordination frameworks with the empirical formula [{Ln₄(ip)₇(H₂O)₂}{Cu(bpy) ₂}₂]_n [Ln=Nd (1), Sm (2), Eu (3)]. Single-crystal X-ray diffraction analyses reveal that they are isostructural and possess a 3D cavity framework with two complex cations [Cu(2,2′-bpy)₂]⁺ encapsulated in each cavity. TGA curve shows that they are highly thermally stable. Magnetic studies illustrate weakly antiferromagnetic exchange interactions between lanthanide(III) ions at room temperature in 1-3. Compound 2 has interesting photoluminescent property owing to the coexistence of host and guest photoluminescent units.
