Raising the operating temperatures of single-molecule magnets is important toward the aim of realizing their potential applications such as in high density information storage and computing. Synthetic strategies are required that allow the increase of the thermal barrier to spin relaxation while simultaneously suppressing undesirable alternative relaxation pathways such as quantum tunneling of the magnetization. Blocking temperatures may be improved by either matching ligand field symmetry with the maximal <i>M</i><sub>J</sub> state electron distribution for the design of mononuclear lanthanide single-molecule magnets or by engendering strong magnetic exchange coupling in multinuclear lanthanide complexes. Here, we will present the synthesis of radical-containing lanthanide single-molecule magnets and describe effective suppression of quantum tunneling pathways using organic bridging radical ligands.
