Self‐assembled supramolecular complexes that contain paramagnetic transition metal ions, such as that illustrated below, can be structurally characterized by the precise measurement of the separation between metal centers and spin labels. The technique, which employs double electron electron resonance (DEER), should also be applicable to metalloproteins.
