The first examples of digallium compounds that feature both organo and
halo substituents, [Li(THF)(4)][Ar'(Cl)GaGaCl3] (1) and Ar'(Cl)GaGa(C
l)Ar' (2), have been prepared by reaction of Ga2Cl4 . 2 dioxane with L
iAr' (Ar' = 2,4,6 -(1)Bu(3)C(6)H(2)). The Ga2Cl2 skeleton of 2 is plan
ar with a dihedral angle of 180 degrees.
