Abstract

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 AlMe₃ 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···F interaction in the solid state has a stabilization effect and the species [NaAlMe₃L]₂ can de isolated for the first time, which was not possible when using Schiff bases without electron withdrawing substituents as ligands

摘要

已经使用具有吸电子取代基的席夫碱作为配体制备了新的杂金属铝-碱金属化合物。这些新物种的合成是通过 AlMe₃与新制备的碱金属化配体反应实现的。形成的衍生物通过溶液中的 NMR 和固态中的单晶 X 射线衍射进行了表征。制备了带有锂和钠的铝酸盐衍生物，并观察到最终产物中碱金属的明显影响。在固态中存在 Na···F 相互作用具有稳定化效应，可以首次分离出 [NaAlMe₃L]₂ 物种，而使用没有吸电子取代基的席夫碱作为配体则不可能。
