摘　　要：m-Benzoquinones are often regarded as unstable materials in the form of radicals.Herein,an air-stable small molecular m-benzoquinone[4,6-diamino-1,3-benzoquinone(4,6DA1,3BQ)]without bulky groups or large conjugated systems is reported,and its chemical structure and state are profoundly elucidated by a series of substantial investigations that indicate their presence as zwitterions rather than as diradicals.
