Subnanosecond ion‐pair lifetimes have been observed for the electrostatic attachment of divalent spin‐carrying counterions to oppositely charged, rodlike Ru II 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).
