Abstract
Crystals of quinhydrone, which is a typical charge-transfer complex, composed of hydroquinone and p-benzo-quinone, can be produced by electrolytic oxidation of hydroquinone. In situ observation of the electrochemical crystal growth of quinhydrone was performed in a thin-layer cell filled with aqueous solution of NaCl. Hexangular prisms characteristic of quinhydrone were observed to grow at different places apart from the anode.
