Chlorine dioxide forms red-colored (λ(max)=480 nm) CT complexes with persistent piperidine and imidazoline nitroxyl radicals in diethyl ether, n- pentane, carbon tetrachloride, methylene chloride and on silica gel surface. Equilibrium constants, enthalpy and entropy of formation and extinction coefficient of the complex between ClO2 and 2,2.6,6-tetramethyl-4- oxypiperidin-1-oxyl 1 in diethyl ether were deter- mined. In Et2O the complex is stable under normal conditions, in other media it transforms into the oxoammonium salt.
