| 摘 要： | 设计合成了2个结构新颖的半夹心单核聚吡唑硼酸盐羧酸配合物Tp*Co(Hglu)(CH3OH)(1)和Tp*Co(Hsub)(H2O)(2)Tp*=三聚(3,5-二甲基吡唑)硼酸根, H2glu=戊二酸, H2sub=辛二酸], 并通过元素分析、 红外光谱、 紫外-可见光谱和X射线单晶结构分析对标题配合物进行了表征. 结构分析表明, 在配合物1和2中, 配体Tp*都是三齿配位, 配位模式相同; 戊二酸和辛二酸都以μ1-η1-η1的端基配位模式与金属相连. 此外, 还对配合物的热稳定性进行了详细分析, 并初步探讨了配合物催化氧化环己烷的催化活性.

| Abstract: | Two new mononuclear complexes Tp*Co(Hglu)(CH3OH)(1) and Tp*Co(Hsub)(H2O)(2) have been synthesized successfully. The complexes were characterized by elemental analysis, IR, UV-Vis spectroscopy and single-crystal X-ray diffraction. Structural analysis reveals that in complexes 1 and 2, the coordination mode of the ligand Tp* is terminal tridentate chelated coordination mode. While the glutaric or suberic acid ligand adopt a μ2-η1-η1 linking fashion. In addition, the thermal stability and the activity in catalytic oxidation of cyclohexane have been discussed. |
