Look both ways : Coordination bonding of verdazyl radicals to diamagnetic metal ions dramatically modifies the crystal packing of the electronic spin bearers. The face‐to‐face positioning of two radicals leads to a magnetic behavior that is more relevant to a S =0 to S =1 spin‐transition phenomenon than to the usual exchange‐interaction view.
