 Title    Nitrogen Compounds of Elements of the Third Main Group with Intra-and Intermolecular Donor Acceptor Bonds, V [1] Special Gallium and Indium Amides with Alkoxo Groups  
 Abstract    The lithium alkoxoamidosilane (Me2Si(O r Bu)(N r Bu)Li)2 (4) and its trimethyltin derivative Me2Si(0'Bu)(N'Bu)SnMe3 (7) have been used, to introduce the ligand Me2Si(0'Bu)(N'Bu) = L into molecular compounds of gallium and indium. The following molecules were synthesized: L—M(Me)Cl (M = Ga (5), In (6)), L-InMe2 (8), L-InX2 (X = Cl (9), Br (10)), L2InX (X = Cl (11), Br (12)) and L2Ga2Cl2 (22). The ligand L is assumed to chelate the metal atom on the basis of temperature dependent 'H NMR spectra. The chelating effect is more pronounced in the gallium derivatives than in the indium analogues. Equilibria between L2InX/InX, and LInX: have been observed in diethylether solutions. No metal(I) derivatives LGa or Lin could be isolated. L2Ga2Cl2 (22), formally containing gallium(ll), can be sublimed without decomposition at 110 °C in vacuo.
