摘要

In contrast to its behavior in aqueous solution, the [IrCl6]2-/ [IrCl6]3-system exhibits classical reversible, uncomplicated electrochemical behavior at glassy-carbon electrodes in the basic aluminum chloride-1-methyl-3-ethylimidazolium chloride room-temperature ionic liquid. The formal potential of this redox system in the 49.0/51.0 mol % melt was found to be 0.370 V vs. A1 in the 66.7/33.3 mol % melt. Diffusion coefficients for [IrCl6]2-and [IrCl6]3-in the former melt were 4.3 X 10-7and 3.0 X 10-7cm2s-l, respectively, at 40.0 °C. The Stokes-Einstein product for [IrCl6]2-in the ionic liquid was remarkably close to its value in aqueous solution.
