摘要
由侧链带有噻吩的环戊二烯基配体C5H5C6H10C4H3S与Fe(CO)5在二甲苯中加热回流,合成了1个新颖的四羰基二铁配合物[(η5-C5H4)C6H10(C4H3S)Fe(CO)2]2。通过元素分析、IR、1H NMR对其结构进行了表征,用X-射线单晶衍射确定了其结构。X-射线单晶衍射表明配合物中有2个桥羰基和2个端羰基,Fe-Fe的键长为0.25465(10)nm。
The reaction of the thienyl side chain functionalized cyclopentadienyl ligand C5H5C6H10C4H3S with Fe(CO)5 in refluxing xylene gave the novel cyclopentadienyl tetracarbonyl diiron compound [(η5-C5H4)C6H10(C4H3S)Fe(CO)2]2.The structure of the compound was characterized by elemental analysis,IR,1H NMR spectra and X-ray single crystal diffraction.The X-ray crystal structure indicates the structure with bridging and terminal CO groups and the bond length of Fe-Fe is 0.254 65(10) nm.CCDC: 768950.
