title: A supramolecular switch between ground high- and low-spin states using 2,2':6',2''-terpyridine-6,6''-diyl bis(tert-butyl nitroxide).
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.
