A designed room-temperature triplet ligand from pyridine-2,6-diyl bis(tert-butyl nitroxide)†
Abstract
The magnetic study on newly developed 4-mesitylpyridine-2,6-diyl bis(tert-butyl nitroxide) shows that almost the whole population has a ground triplet state at room temperature, and the ability of complex formation as a tridentate triplet ligand was proven with a diamagnetic yttrium(III) ion.
