Formation of the Digallium Compound [(C5C6)2N3](R)Ga–Ga(R)[N3(C6H5)2] with Two Bis(trimethylsilyl)methyl Groups and Two Terminal Chelating Diphenyltriazenido Ligands

Tetrakis[bis(trimethylsilyl)methyl]digallane (4) 1 reacts with 1,3‐diphenyltriazene to yield two compounds, which were both characterized by a crystal structure determination. The gallium–gallium bond is retained in the yellow derivate [(H5C6)2N3](R)Ga–Ga(R)[N3(C6H5)2 2 [R = CH(SiMe3)2], which is formed by a ligand exchange reaction and shows two terminal chelating triazenido ligands besides two bis(trimethylsilyl)methyl groups; the GaGa bond length is 245.79(6) pm. The second product is the orange dialkyl(diphenyltriazenido)gallium derivative R2Ga[N3(C6H5)2] 3, where the triazene has reacted as an oxidant by the cleavage of the GaGa bond and probably by release of elemental hydrogen.
