The organoaluminium and -gallium hydroxylamides (Me2GaONMe2)2, (tBu2AlONMe2)2, (tBu2GaONMe2)2 and (Me2AlONiPr2)2 have been prepared by the reaction of the hydroxylamines Me2NOH and iPr2NOH with the trialkylmetal compounds trimethylgallium, tri-tbutylaluminium and tri-tbutylgallium, respectively. All compounds have been characterised by NMR spectroscopy (1H, 13C, 15N, 17O and 27Al), by mass spectrometry and elemental analyses. The crystal structures of the four compounds have been determined, showing that they all form dimers but with different modes of aggregation: (Me2GaONMe2)2 has a Ga2O2N2 six-membered ring, (tBu2AlONMe2)2 and (Me2AlONiPr2)2 have Al2O2 four-membered rings, (tBu2GaONMe2)2 forms a Ga2O2N five-membered ring.

有机铝和
镓的
羟胺盐(Me2GaONMe2)2、(tBu2AlONMe2)2、(tBu2GaONMe2)2和(Me2AlONiPr2)2。所有化合物均通过NMR光谱(1H、13C、15N、17O和27Al)、质谱和元素分析进行了表征。四个化合物的晶体结构已经确定,显示它们都以二聚体形式存在,但聚集模式不同:(Me2GaONMe2)2具有六元环Ga2O2N2,(tBu2AlONMe2)2和(Me2AlONiPr2)2具有四元环
Al2O2,而(tBu2GaONMe2)2则形成五元环Ga2O2N。
