  A Novel Organolead(II) Species, the Plumbacycloalkane Derivative [CH₂SiMe₂C(SiMe₃)₂PbC(SiMe₃)₂SiMe₂CH₂]

  摘要：

  The title lead(II) derivative was obtained as dark blue crystals by treatment of PbCl2 with [Li(TMEDA)(2)][CH2SiMe2C(SiMe3)(2)LiC(SiMe3)(2)SiMe2CH2] (TMEDA = N,N,N',N'-tetramethylethylenediamine) in tetrahydrofuran and its structure determined by X-ray diffraction. The compound is in. effect the first dialkylead(II) species to be structurally characterized. The C-Pb-C angle is 117.1(2)degrees. Analogous treatment of SnCl2 yielded a yellow solid, which was judged from spectroscopic data to be the TMEDA complex of the analogous stannacycloalkane.
