摘要
配体[C5Me4HR][R=4-Br Ph(1),(Me C5H3N)CH2(2)]分别与Mo(CO)6,Ru3(CO)12和Fe(CO)5在二甲苯中加热回流,得到了6个双核配合物trans-[η5-C5Me4R]2Mo2(CO)6(3,4),trans-[(η5-C5Me4R)Ru(CO)(μ-CO)]2(5,6)和trans-[η5-(C5Me4R)Fe(CO)(μ-CO)]2(7,8)。通过元素分析、红外光谱、核磁共振氢谱对配合物的结构进行了表征,并用X-射线单晶衍射法测定了配合物3,5,6和8的结构。
Via thermal reactions of the substituted tetramethylcyclopentadienes [C5Me4HR] [R =4-Br Ph(1),(Me C5H3N)CH2(2)] with Mo(CO)6,Ru3(CO)12and Fe(CO)5,respectively in refluxing xylene,the responding dinuclear metal carbonyl complexes trans-[η5-C5Me4R]2Mo2(CO)6(3,4),trans-[(η5-C5Me4R)Ru(CO)(μ-CO)]2(5,6),and trans-[η5-(C5Me4R)Fe(CO)(μ-CO)]2(7,8) have been obtained.These complexes have been characterized by elemental analysis,IR,and1 H NMR spectra.The crystal structures of 3,5,6 and 8 have been determined by X-ray crystallography.CCDC:934733,3;944267,5;926404,6;926405,8.
