合成了三个单核金属配合物[M-II（L-N_3 O_2）（MeCN）（2）][BPh_4]（2）（M = Fe，1; Co，2; Ni，3），并对其结构进行了表征。磁性研究显示1（D = -17.1 cm（-1））和3（D = -14.3 cm（-1））的单轴磁各向异性和2（D = +36.9 cm（-1））的易平面磁各向异性。在外加磁场下观察到配合物1和2的慢磁弛豫，这两者都是由拉曼过程主导的。
Three mononuclear metal complexes [M-II(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.
