Three mononuclear metal complexes [MII(L-N3O2)(MeCN)2][BPh4]2 (M = Fe, 1; Co, 2; Ni, 3) were isolated and structurally characterized. Magnetic studies revealed uniaxial magnetic anisotropy for 1 (D = -17.1 cm-1) and 3 (D = -14.3 cm-1) and easy-plane magnetic anisotropy for 2 (D = +36.9 cm-1). Slow magnetic relaxation was observed for complexes 1 and 2 under an applied magnetic field, both of which are dominated by a Raman process.
三种单核金属配合物[MII(L-N3O2)(MeCN)2][BPh4]2（M = Fe，1；Co，2；Ni，3）被分离并进行了结构表征。磁性研究表明，1（D = -17.1 cm-1）和 3（D = -14.3 cm-1）具有单轴各向异性磁各向异性，而 2（D = +36.9 cm-1）具有易面各向异性磁各向异性。在施加磁场的情况下，观察到配合物 1 和 2 的缓慢磁弛豫，这两种弛豫都由拉曼过程主导。
