Magnetic bistability spanning over a temperature domain of 40 K can result from a small structural deformation of the gadolinium aminoxyl coordination. This is illustrated for a nitronyl nitroxide 3d–4f chain, [Ln­(hfac)3Cu­(hfac)2(NIT-Pyrim)2] (LnIII = Gd, Dy), which is the first example of a bistable lanthanide-based complex.
