Abstract

Three novel lanthanide-organic frameworks, [Ln₃(μ ₃-OH)₂L₂(HCO₂)₃(H ₂O)₂]·H₂O (Ln = Eu (1), Gd (2), Dy (3); H₂L = 3,3′-dimethoxy-4,4′-biphenyldicarboxylic acid), have been prepared by the solvothermal reaction of Ln(NO₃) ₃·6H₂O and H₂L in DMF/H₂O mixed solvent. Crystallographic data show that 1-3 are isomorphous and crystallize in the monoclinic space group P2₁/c. Each complex contains a rare infinite nanosized ribbon [Ln₃(μ₃-OH) ₂(-CO₂)₆]⁺_n with three crystallographically distinct Ln(iii) ions: two nine-coordinated and one eight-coordinated. The nanosized ribbons are interconnected through HCO ₂^- anions and L^2- linkers to yield a 3D framework. Furthermore, 1 exhibits strong red luminescence upon 343 nm excitation. The investigation of the magnetic properties shows the weak antiferromagnetic coupling between Gd(iii) ions in 2 but ferromagnetic coupling between the Dy(iii) ions in 3.
