文摘

As a continuity of the [Cu^II(AIB)(bpy)(H₂O)](ClO₄)₂-containing (1) ACCO (1-aminocyclopropane-1-carboxylate oxidase) model, two new copper(II)–amino acid complexes [Cu^II₂(AIB)₂(PBI)₂(CH₃OH)(ClO₄)]ClO₄ (2) and [Cu^II₂(AIB)₂(PBT)₂(H₂O)](ClO₄)₂·CH₃OH (3) with a modified hetero-bidentate ligands (PBT = 2-pyridin-2-yl-benzothiazole and PBI = 2-pyridin-2-yl-1H-benzoimidazole) have been synthesized, characterized by various techniques including IR, UV–Vis, electrochemical and X-ray measurements, and investigated their reactivity toward H₂O₂ with respect to the redox behavior compare to 1.
