摘要：
Dehalogenation of tmp(2)GaCl (tmp = 2,2,6,6-tetramethyl piperidino group) with sodium/ potassium alloy leads to the digallane (tmp)(2)Ga-Ga(tmp)(2) as a pale yellow solid. Alternatively this digallane is prepared in good yields by reaction of four equivalents of tmpLi with Ga2Cl4.2 dioxane. Ga-2(tmp)(4) is characterized by MS, NMR (H-1 and C-13) and X ray structure determination. The gallium-gallium bond length is 252.5(1) pm and its two GaN2 units are twisted by 31 degrees against each other.
