Abstract: Several advances in the coordination chemistry of
stable free-radical species over the past six years are documented in
this review article. Specifically, a number of recent reports focused
on the coordination chemistry of chelating nitroxide ligands are highlighted,
with an emphasis on enhanced magnetic or optical properties in these
complexes. Furthermore, very intriguing recent magnetic and optical
studies with one-dimensional nitroxide chain complexes (new "Glauber"
chains and chiral magnets) are also discussed. The verdazyls
are another family of stable radicals whose coordination chemistry was
literally unexplored prior to 1997. A summary of recent reports discussing
metal-verdazyl coordination complexes is also presented, followed by
an eye to the future of stable radical design and the coordination chemistry
of these interesting molecules.
