The reactions of [LGa–GaL] (L = dpp-bian = 1,2-bis[(2,6-di-isopropylphenyl)imino]acenaphthene) with ammonia and pyrrolidine in toluene lead to the formation of adducts [L(NH3)Ga–Ga(NH3)L], [L(HNC4H8)Ga–GaL] and [L(HNC4H8)Ga–Ga(HNC4H8)L], respectively. In contrast, the reaction between crystalline digallane and an excess of pyrrolidine leads to the formation of compound [LGa(NC4H8)(HNC4H8)]. The complex [LGa(C5H5N)(μ-O)Ga(C5H5N)L] was obtain from reaction of digallane with N2O in the presence of pyridine.
