摘要: Abstract Four new lanthanide–carboxylate coordination polymers of the formula [Ln3L4(phen)4(H2O)4](ClO4)·2H2O, (Ln = Dy (1), Tb (2), Ho (3) and Er (4), L = 2,3-naphthalenedicarboxylate phen = 1,10-phenanthroline) were solvothermally synthesized. Their structures as well magnetic photoluminescent properties completely investigated. Complexes 1–4 are isostructural exhibit 1D ribbon-like chains with envelope-like sixteen-membered rings. The DyIII TbIII complexes show corresponding characteristic luminescence in visible region ErIII complex shows near-infrared upon excitation UV rays. Studies on reported. Dy(III) analog 1 exhibits slow relaxation could be a example SMM (single molecule magnet).
