Abstract

Self-assembly of Cu(OTf) ₂ with a new N,N′,N″-((benzene-1,3,5-triyltris(oxy))tris(benzene-2,1-diyl))trinicotinamide ligand (L) in a mixed solution gives rise to single crystal of [Cu ₂ L ₂ (OTf) ₃ (Sol)(H ₂ O) ₂ ]OTf (Sol = Me ₂ CO, H ₂ O, MeOH) cages. Their skeletal structure is a bimetallic cage with copper (II) (Cu(II)) sites of corresponding coordinated solvate molecules. These crystals have been employed as hetero-catalysts for 3,5-di-tert-butylcatechol oxidation, showing significant and different catalytic effects in dichloromethane according to the coordinated solvate molecules in the order Sol = Me ₂ CO > MeOH > H ₂ O. Such notable catalytic effects can be explained by the dissociation ability of coordinated solvate molecules at the catalytic center.
