Abstract

Biradical 2,2′:6′,2′′-terpyridine-6,6′′-diyl bis(tert-butyl nitroxide) (tpybNO) showed intramolecular ferromagnetic coupling with 2J/kB = +2.14(10) K and its complex [Zn(tpybNO)(MeOH)2](BF4)2 exhibited intramolecular antiferromagnetic coupling with 2J/kB = −7.5(4) K, suggesting exchange coupling switchable by means of supramolecular chemistry.
