Gallyl lanthanide complexes containing unsupported Ln–Ga (Ln = Sm, Eu, Yb or Tm) bonds†
Abstract
A series of bis(gallyl) lanthanide(II) complexes, [LnII{Ga[(ArNCH)2]}2(tmeda)2] (Ln = Sm, Eu or Yb; Ar = C6H3Pri2-2,6), and a gallyl thulium(III) compound, [TmIII{Ga[(ArNCH)2]}{(ArNCH)2}(tmeda)], have been prepared; the first structural studies of Ga–Tm and Ga–Sm bonded complexes are described.
