Five isomorphous lanthanide-organic frameworks based on 3-carboxymethoxy phenyl acrylic acid (H2L), [LnL(HCOO)(H2O)](n) (Ln = La(1), Ce(2), Pr(3), Nd(4), Y(5)), have been hydrothermally synthesized. X-ray structural analysis reveals that these complexes are rare organic-inorganic hybrid frameworks with unusual (3, 4, 7)-connected (4(2).6) (4(4).6(2)) (4(9).6(8).8(4)) topology. Moreover, the magnetic properties of 2 and 3 were also investigated and suggested that the thermal depopulation of the crystal-field energy levels of the multiplet, and the antiferromagnetic interactions between Ln(3+) ions.
