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, [((But)MesNacnac)ECl] ((But)MesNacnac = [(MesNCBu(t))(2)CH](-); 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, [{((But)MesNacnac)Sn}(2)].
