Unprecedented infinite lanthanide hydroxide ribbons interconnected by Pra2biim(2-) (H2Pra2biim = 1'-di(propionic acid)-2,2'-biimidazole) into 3-D [Ln3(μ3-OH)3(Pra2biim)3 (H2O)2]n·4nH2O (Ln = Nd, Pr and La) have been achieved by utilizing the unique H2Pra2biim-Ln(3+) hydrolysis system. The Ln···Ln antiferromagnetic coupling with magnetic anisotropy has been observed.
