Abstract
The complexing behavior of 1,1 " :1 ' ,1 ' ' ' -bis(1,4,10,13-tetraoxa-7,16 -diazacyclooctadecane-7,16-diyldimethyl)bisferrocene (I) toward KPF6 ion wa s studied. To gain a better understanding into the factors which determine the extent of this redox-switched bonding in the complexation of KPF6 by 1, we carried out X-ray crystal structural determination, NMR, FAB-MS techniq ue, cyclic voltammetry measurements, and Fe-57 Mossbauer analyses. We sugge st that the KPF6 salt of 1 is not a kinetically labile system. Our studies also provide direct evidence that ferrocene crown ether displays a drop in complex stability upon oxidation.
