摘要：
Treatment of MCl2 (M = Ge or Sn) with 2,6-bis(benzimidazol-2-yl) pyridine (G-BZIMPY, G = NBn, N(3,5-CF3) Bn, NAllyl and O) yielded the self-ionization products [G-BZIMPYMCl][MCl3] (1-6) in high yields (75-98%). Reduction reactions are examined and the nickel complexes 8 and 9 ([(NBnBZIMPY) Ni-2][MCl3](2)) are isolated from the reaction of Ni(COD)(2) with 1 and 2 respectively. [NBn-BZIMPYSnCl][SnCl3] shows a significantly stronger MLCT band in the UV-vis absorption spectrum than its germanium counterparts, with germanium complexes exhibiting negative solvatochromism that is not observed in tin complexes.
