摘要 详细研究了[Re2(CO)10]在氧化三甲胺(TMNO.2H2O)的作用下与配体H2NCH2CH2OH的反应,反应产物用丙酮-己烷混合溶剂重结晶,得到Re(Ⅰ)双核配合物[Re2(-μOCH2CH2NCMe2)2(CO)6].采用元素分析、红外光谱和1H NMR对配合物的结构进行了表征.用SMART CCD X射线衍射仪测定了晶体结构,结果表明该晶体属三斜晶系,Pī空间群.在此晶体结构中,2个铼离子被2个氧桥联形成二聚单元,每个Re(Ⅰ)是六配位的变形八面体构型. The complex [Re2（-μOCH2CH2NCMe2）2（CO）6]. has been synthesized and characterized. The crystal structure was determined by single X-ray diffraction analysis. The results show that it belongs to triclinic crystal system, Pi space group. X-ray crystallography studies show the complex is a dimer as a result of two O bridging. In the bi-rhenium（I） complex, each Re atom adopts a distorted octahedral geometry.
