Abstract
A dysprosium(III) sandwich complex, [Dy(III)(COT″)(2)Li(THF)(DME)], was synthesized using 1,4-bis(trimethylsilyl)cyclooctatetraenyl dianion (COT″). The complex behaves as a single-ion magnet and demonstrates unusual multiple relaxation modes. The observed relaxation pathways strongly depend on the applied static dc fields.
摘要
一种钆（III）夹心配合物，[Dy(III)(COT″)(2)Li(THF)(DME)]，使用 1,4-双（三甲基甲硅烷基）环辛四烯二阴离子（COT″）合成。该配合物表现为单离子磁体，并表现出异常的多种弛豫模式。观察到的弛豫途径强烈依赖于所施加的静态直流磁场。
