Like a molecular toggle switch , the bridging azide ion in a highly preorganized dinickel( II ) complex turns strong antiferromagnetic coupling on or off (see picture). Single crystals of the compound stay intact over the entire temperature range studied and feature hysteretic bistability not far from ambient temperature.
