Reaction of complex [CpRu(pyr)3][PF6] (3) with the NHC carbene IPr (IPr = 1,3-bis(2,6-diisopropylphenyl)imidazol-2-ylidene) results in the NHC complex [Cp(IPr)Ru(pyr)2][PF6] (4), which was studied by NMR specroscopy and X-ray diffraction analysis. Reaction of [Cp(IPr)Ru(pyr)2][PF6] (4) with LiAlH4 leads to the trihydride Cp(IPr)RuH3 (5) characterised by spectroscopic methods. Heating compound 5 with hydrosilanes gives the dihydrido silyl derivatives Cp(IPr)RuH2(SiR3) (6). Systematic X-ray diffraction studies suggest that complexes 6 have stronger interligand Si∙∙∙H interactions than the isolobal phosphine complexes Cp(Pr3P)RuH2(SiR3).
配合物[CpRu(pyr)3][PF6] (3) 与NHC卡宾IPr（IPr = 1,3-双(2,6-二异丙基苯基)咪唑-2-亚基）反应生成NHC配合物[Cp(IPr)Ru(pyr)2][PF6] (4)，通过核磁共振光谱和X射线衍射分析对其进行了研究。[Cp(IPr)Ru(pyr)2][PF6] (4) 与LiAlH4反应生成三氢化物Cp(IPr)RuH3 (5)，通过光谱方法对其进行了表征。化合物5与硅烷加热反应得到二氢硅烷基衍生物Cp(IPr)RuH2(SiR3) (6)。系统的X射线衍射研究表明，配合物6的配体间Si∙∙∙H相互作用比等瓣膦配合物Cp(Pr3P)RuH2(SiR3)更强。
