• Treatment of MCl 2 (M = Ge or Sn) with 2,6-bis(benzimidazol-2-yl)pyridine (G-BZIMPY, G = NBn, N(3,5-CF 3 )Bn, NAllyl and O) yielded the self-ionization products [G-BZIMPYMCl][MCl 3 ] ( 1-6 ) in high yields (75-98%). Reduction reactions are examined and the nickel complexes 8 and 9 ([(NBn-BZIMPY) 2 Ni][MCl 3 ] 2 ) are isolated from the reaction of Ni(COD) 2 with 1 and 2 respectively. [NBn-BZIMPYSnCl][SnCl 3 ] 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. Variants of the 2,6-bis(benzimidazol-2-yl)pyridine ligand are used to synthesize novel group 14 complexes of germanium and tin. The salts are characterized by X-ray crystallography, NMR, UV-vis, and the Lewis acidity of some examples are probed.
