Amine-elimination gave the two uraniumârhenium complexes [(TsXy)(THF)nURe(η5-C5H5)2] [TsXy = HC(SiMe2N-3,5-Me2C6H3)3; n = 0 or 1]; structural and theoretical analyses, and comparison to [(TrenTMS)URe(η5-C5H5)2] [TrenTMS = N(CH2CH2NSiMe3)3], reveal an increasing Ï-component to the UâRe bond upon removal of dative ancillary ligands from uranium with the Ï-component remaining essentially invariant.

铼配合物 [(TsXy)(THF)nURe(η5-
C5H5)2] [TsXy = HC(SiMe2N-3,5-Me2C6H3)3; n = 0 或 1];结构和理论分析,以及与 [(TrenTMS)URe(η5- )2] [TrenTMS = N(CH2CH2NSiMe3)3] 的比较,显示在去除
铀的配位辅助
配体时,U-Re 键的σ成分增加,而π成分基本保持不变。
