Bis(ferrocenyl) derivatives 3a, 3c and 3d containing secondary chelating substituents act as efficient voltammetric sensors of Mg2+ and Zn2+ ions in acetonitrile solution in concentrations as low as 10 mol%: a new redox peak appears in the cyclic voltammogram, positively shifted by 170-225 mV for 3a, 160-175 mV for 3c and 160-170 mV for 3d. Compounds 3b and 4 are selective for Zn2+ (215 mV shift) and Mg2+ (205 mV shift) ions, respectively, whilst 3d is also responsive to Ca2+ ions (165 mV shift) with no interference from a large excess of several other metal salts. The X-ray crystal structure of 3a is also reported.
