[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.
[Sm(hfac)3(boaDTDA)]n是首个表现出铁磁有序性的基于噻唑基中性自由基配体的配位化合物；居里温度TC = 3 K。[Sm(iii)-自由基]n物种可溶于常见有机溶剂，且能定量升华。麦康奈尔I机制涉及对合作磁性质有贡献的局域交换途径。
