| 摘 要： | tBuN=TaCl3(py)2]和氮杂环卡宾(IPr =1,3-bis(2,6-diisoproylphenyl)imidazol-2-ylidene)的反应得到预料之外的叔丁基亚胺四氯合钽(V)离子配合物IPrH]+tBuN=TaCl4(py)]- (1)。利用核磁共振波谱,红外吸收光谱,荧光光谱,元素分析和X-Ray单晶衍射对配合物1的结构进行了表征。X-射线单晶衍射分析表明,Ta(V)中心与4四个氯和2个分别来自亚胺和吡啶配体的氮原子以八面体构型配位。

| Abstract: | IPrH]+tBuN=TaCl4(py)]- (1) (IPr=1,3-bis(2,6-diisoproylphenyl)imidazol-2-ylidene) was obtained unexpe-ctedly by the reaction of tBuN=TaCl3(py)2 and IPr. Complex 1 was structurally characterized by NMR, IR, fluores-cence spectra, elemental analysis and single-crystal X-ray diffraction. The crystal structure of 1 shows that the Ta(V) center is octahedrally coordinated by four chlorides and two nitrogen atoms from imido and pyridyl ligands, respectively. CCDC: 873803. |
