| Abstract: | The binding of Na+, K+ and Mg2+ to benzo-15-crown-5 and aza-15-crown-5 directly-linked ferrocenes results in shifts of the ferrocene oxidation wave to more positive potentials. The magnitude of these anodic shifts is related to the charge/radius ratio of the cationic guest. The results of an X-ray diffraction study of the structure of a ferrocene benzo-15-crown-5 sodium complex are also reported. |
