A novel pentadentate ligand based on a 2,2'-bipyridine template and functionalized with two methylene bridged nitroxide arms provides mononuclear Cu(II) and Zn(II) complexes displaying a facial and meridional conformation, respectively; for Cu large intramolecular ferromagnetic (J/kB = +173 K) and antiferromagnetic (J'/kB = -170 K) exchange interactions are evidenced from magnetic measurements.
