Abstract: Different structures of FOX-7 in various solutions play a crucial role in the mechanism of its electrochemical reduction. In aprotic solvent the irreversible four-electron, four-proton reduction of one nitro group proceeds according to the autoprotonation mechanism. The zwitterionic form of FOX-7 serves as a source of protons. The two-step reduction is accompanied by an adsorption step in dependence on used solvent and material of electrode. The in situ spectroelectrochemical measurements revealed formation of a dianion radical intermediate with alternating line-width effect. The intramolecular dynamic processes were described by temperature dependent in situ ESR measurement.
