β-氰乙基-α-二茂铁邻卤代苄基醚的晶体和分子结构

THE CRYSTAL AND MOLECULAR STRUCTURE OF β-CYANOETHYL-α-FERROCENYLHALOGENBENZYL ETHERS

本文应用X射线单晶衍射方法测定了系列β-氰乙基-α-=茂铁邻卤(氟、氯、溴、碘)代苄基醚的晶体结构,描述并讨论了由卤原子变更所引起的分子结构差异。结果表明,取代卤原子种类不同,导致了该系列化合物分属于两种分子构型。

We have reported the structure of β-cyanoethyf-a-ferrocenylfluorobenzyl ether. Present study is concerned with the crystal and molecular structures of serious β-cyanoethyl-α-ferrocenylhalogenbenzyl ethers (C_5H_5FeC_5H_4CH (OCH_2CH_2CN)C_6H_4X) (X = F, Cl,Br,I).All crystals were solved with direct method and fourier synthesis. The differences of the structures caused by the different halogen atoms are discussed. The results have shown there are two types of molecular configuration. A for X = F and B for X = Cl,Br,I.
