Herein, we report a new trigonal prismatic cobalt(II) complex that behaves as a single molecule magnet. The obtained zero-field splitting, which is also directly accessed by THz-EPR spectroscopy (-102.5 cm ), results in a large magnetization reversal barrier U of 205 cm . Its effective value, however, is much lower (101 cm ), even though there is practically no contribution from quantum tunneling to magnetization relaxation.
在此，我们报道了一种表现为单分子磁体的新型三棱柱钴（II）配合物。所获得的零场分裂（通过太赫兹电子顺磁共振光谱也可直接测得，为 -102.5 cm⁻¹）导致了高达205 cm⁻¹的大磁化反转势垒U。然而，其有效值要低得多（101 cm⁻¹），尽管量子隧穿对磁化弛豫几乎没有贡献。
