Description

<jats:title>Abstract</jats:title> <jats:p>The reaction of Zn(ClO4)2·6H2O with TPA and H4THBQ in methanol gave air-sensitive crystalline powder [Zn2(μ-H2THBQ)(TPA)2](ClO4)2 (1). An equimolar reaction of 1 with 1,4-benzoquinone (BQ) in acetonitrile under Ar atmosphere quantitatively produced 1,4-hydroquinone and [Zn2(μ-RHOD)(TPA)2](ClO4)2 (2) as a result of the 2H+, 2e proton-coupled electron-transfer (PCET) reaction.</jats:p>
