Synthesis and Crystal Structure Analysis of Tetraphosphanylsilane and Identification of Tetraphosphanylgermane
摘要:
Inversion-symmetric pairs, each with two weak P-H⋅⋅⋅P interactions, form molecules of Si(PH2 )4 in the crystal (see drawing). The title compounds are formed from ECl4 (E=Si,Ge) on reaction with [LiAl(PH2 )4 ] and could serve as single-source CVD precursors for phosphides.
