Contrasting reductions of group 14 metal(ii) chloride complexes: synthesis of a β-diketiminato tin(i) dimer

Abstract

Reductions of the β-diketiminato group 14 metal(II) chloride complexes, [(^ButMesNacnac)ECl] (^ButMesNacnac = [(MesNCBu^t)₂CH]⁻; Mes = mesityl; E = Ge, Sn or Pb), with a magnesium(I) dimer have led to differing outcomes, which include the formation of the first β-diketiminato group 14 metal(I) dimer, [{(^ButMesNacnac)Sn}₂].
