The reaction of [EtGa(NMe2)2]2 with neat, excess EtNH2 afforded a glassy solid whose IR spectrum did not exhibit any N-H absorptions and 1H NMR spectrum indicated the presence of more than one compound. Refluxing a toluene solution of this solid afforded the imido gallium compound, (EtGaNEt)6 (1), in 56% yield. Compound 1 crystallize d in space group R3̄ with a hexagonal prismatic structure constructed with two planar Ga3N3 rings.
