| 摘 要： | The novel octadecanudear Cu-RE cluster haw been isolated from the reaction system of aqueous Cu2+-RE3+-pyb (RE=Sm, Eu; pyb=pyridine betaine) and characterized by single-crystal structural analysis. The results show that the clusters comprise a [Cu12RE6(μ3-OH)24(μ12-ClO4)]17+ octahedral core, which encapsulates a ClO4- ion and has 18 water molecules and 12 bridging pyb carboxylato ligands as external ligands.
