Unprecedented infinite lanthanide hydroxide ribbons [Ln3(μ3-OH)3]n6n+ in a 3-D metal–organic framework†
Abstract
Unprecedented infinite lanthanide hydroxide ribbons interconnected by Pra2biim2− (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–Ln3+ hydrolysis system. The Ln⋯Ln antiferromagnetic coupling with magnetic anisotropy has been observed.
