distances for the open pentadienyl ligand have been found to be about 0.02 A shorter than those for the aromatic pentamethylcyclopentadienyl ligand, whereas for the simple cyclopentadienyl analogue, the Fe–C bond distances for the two ligand types were nearly identical. While the structural data support proposals that the pentadienyl ligand is more strongly bound, the complex reacts readily with silica
摘要确定了Fe(C5Me5)(2,4-C7H11)的结构( =二甲基戊二烯基),并发现其与钌类似物同构。已经发现,开放的戊二烯基配体的Fe–C键距比芳香族五甲基环戊二烯基配体的Fe–C键距短约0.02 A,而对于简单的环戊二烯基类似物,两种配体类型的Fe–C键距几乎相同。尽管结构数据支持戊二烯基配体更牢固地结合,但该配合物容易与二氧化硅气凝胶反应,在此期间,非芳族戊二烯基配体通过质子化作用被去除。固态13 C NMR光谱与将金属掺入一种主要环境中一致,而将其掺入另一种环境的程度较小。
