二烷基镁(Me_3CCH_2)_2、Mg(Me_3SiCH_2)_2和Mg(PhMe_2CCH_2)_2已被分离为结晶固体。后两者不溶于烃类溶液，不挥发，而前者是已知的唯一结晶的、易挥发的、苯可溶的、三聚的镁的二烷基。低温1H和13C-{1H}n.m.r.光谱表明在-80℃时桥端交换很快，并描述了前两种化合物的2：1二乙醚络合物和1：1NNN‘N’-四甲基乙二胺络合物。
The magnesium dialkyls Mg(Me3CCH2)2, Mg(Me3SiCH2)2, and Mg(PhMe2CCH2)2 have been isolated as crystalline solids. The last two are insoluble in hydrocarbon solution and non-volatile whereas the former is the only known crystalline, volatile, benzene-soluble, trimeric dialkyl of magnesium. Low-temperature 1H and 13C-{1H} n.m.r. spectra show that bridge–terminal exchange is rapid at –80 °C. The 2 : 1 diethyl ether complexes of the first two compounds and 1 : 1 NNN′N′-tetramethylethylenediamine complexes are also described.
