Ferromagnetic ordering of –[Sm(III)-radical]n– coordination polymers
Résumé
[Sm(hfac)3(boaDTDA)]n is the first coordination compound of a thiazyl-based neutral radical ligand to exhibit ferromagnetic ordering;
TC = 3 K. The [Sm(III)-radical]n species is soluble in common organic solvents and can be sublimed quantitatively. A McConnell I mechanism is implicated in local exchange pathways that contribute to cooperative magnetic properties.
