In this article we report the synthesis and structure of the new Co(II) complex EtN[Co(hfac)] (I) (hfac = hexafluoroacetylacetonate) exhibiting single-ion magnet (SIM) behavior. The performed analysis of the magnetic characteristics based on the complementary experimental techniques such as static and dynamic magnetic measurements, electron paramagnetic resonance spectroscopy in conjunction with the theoretical modeling (parametric Hamiltonian and ab initio calculations) demonstrates that the SIM properties of I arise from the nonuniaxial magnetic anisotropy with strong positive axial and significant rhombic contributions.
在本文中，我们报道了新型Co(II)配合物EtN[Co(hfac)] (I)（hfac = 六氟乙酰丙酮）的合成与结构，该配合物表现出单离子磁体（SIM）行为。基于静态和动态磁性测量、电子顺磁共振光谱等互补实验技术，并结合理论建模（参数化哈密顿量和从头算）对磁性特征进行的分析表明，I的SIM性质源于具有强正轴向和显著菱形贡献的非单轴磁各向异性。
