抄録

A binuclear tetra-acetate bridged Gd^III complex [Gd₂(μ₂-O₂CMe)₄(H₂L)₂](ClO₄)₂·2H₂O·2MeOH was synthesized, where H₂L = bis(5-methylimidazol-4-yl-methylideneaminopropyl)methylamine. The linear polydentate ligand H₂L functions as a binding group to two Gd^III ions. Two Gd^III ions are bridged by two acetate in η¹:η¹:μ₂ fashion and other two in η²:η¹:μ₂ fashion. The Gd^III⋯Gd^III distance of 3.920(6) Å is shorter than 4.183(1) Å of the bis-acetate bridged Gd^III complex [{Gd^III(O₂CMe)₃(H₂O)₂}₂]·4H₂O. A weak anti-ferromagnetic Gd^III–Gd^III interaction was observed.
