摘要

二、三、四苯基环戊二烯钾与氯化四氢呋喃酸钇在1,3,5-三甲基-1,3,5-三氮杂环己烷（Me3tach）存在下反应得到[Cp' y (Me3tach)Cl2] (Cp' = Ph2C5H3 (CpPh2) (I), Ph3C5H2 (CpPh3) (II), Ph4C5H （CpPh4) (III)）。通过x射线衍射确定了配合物I - III的分子结构(CCDC编号2406644 (I), 2406645 （II), 2406646 (III)）。与环戊二烯配体中苯基取代基的数量无关，所有得到的单环戊二烯配合物的主要结构参数相似。根据核磁共振光谱数据，化合物I和III在THF溶液中保持其结构。

Yttrium Polyphenylcyclopentadienyl Complexes with 1,3,5-Trimethyl-1,3,5-triazacyclohexane

The reaction of di-, tri-, and tetraphenylcyclopentadienylpotassium with yttrium chloride tetrahydrofuranate in the presence of 1,3,5-trimethyl-1,3,5-triazacyclohexane (Me₃tach) gives complexes of the type [Cp'Y(Me₃tach)Cl₂] (Cp' = Ph₂C₅H₃ (Cp^Ph2) (I), Ph₃C₅H₂ (Cp^Ph3) (II), Ph₄C₅H (Cp^Ph4) (III). The molecular structure of complexes I–III was established by X-ray diffraction (CCDC nos. 2406644 (I), 2406645 (II), 2406646 (III)). The main structural parameters of all of the obtained monocyclopentadienyl complexes were similar, irrespective of the number of phenyl substituents in the cyclopentadienyl ligand. According to NMR spectroscopy data, compounds I and III retained their structure in THF solution.
