设计制备了一个新的自旋交叉配合物[Fe(mtt)(phen)(NCS)2·]py。通过元素分析、红外光谱、质谱和紫外光谱等方法对该配合物进行结构表征。变温磁化率研究发现该配合物的自旋转换温度为Tc↑=197K,Tc↓=188K,回滞宽度9K。通过与同体系其他配合物的比较发现,配体的修饰对自旋交叉临界温度以及回滞宽度都有显著影响。
A new spin - cross complex [Fe (mtt) (phen) (NCS) 2 ·] py was designed and synthesized. The complex was characterized by elemental analysis, IR, MS and UV spectra. The results show that the spin conversion temperature of the complex is Tc ↑ = 197K, Tc ↓ = 188K, and the hysteresis width is 9K. Comparisons with other complexes in the same system showed that ligand modification had a significant effect on the critical temperature of spin crossing and the width of hysteresis.
