Description
Summary:New heterometallic aluminium-alkali metal compounds have been prepared using Schiff bases with electron withdrawing substituents as ligands. The synthesis of these new species was achieved via the reaction of AlMe<sub>3</sub> with the freshly prepared alkali-metallated ligand. The derivatives formed were characterized by NMR in solution and by single crystal X-ray diffraction in the solid state. Aluminate derivatives with lithium and sodium were prepared and a clear influence of the alkali metal in the final outcome is observed. The presence of a Na&#183;&#183;&#183;F interaction in the solid state has a stabilization effect and the species [NaAlMe<sub>3</sub>L]<sub>2</sub> can de isolated for the first time, which was not possible when using Schiff bases without electron withdrawing substituents as ligands.
