Subnanosecond ion-pair lifetimes have been observed for the electrostatic attachment of divalent spin-carrying counterions to oppositely charged, rodlike RuII coordination polymers in solution. Continuous wave (CW) EPR and double electron-electron resonance (DEER) spectroscopy show that the spatial distribution of the divalent counterions reflects the spatial distribution of charges on the polyion (see schematic representation).
