The known cyclic dimer, (Me3SiNSiMe2)2 (1), was isolated in the reaction of GaCl3 with one equivalent of Li[N(SiMe3)2] at room temperature as the result of cleavage of a Si-C bond from the N(SiMe3)2 anion. Although the gallium product was not isolated from the GaCl3 reaction, pyrolysis of the new base-stabilized dichloro(silyl)amido gallium compounds, Cl2Ga[N(SiMe3)2](quin) (2) (quin = quinuclidine), Cl2Ga[N(SiMe3)2](NMe3) (3), Cl2Ga[N(SiMe3)(tBu)](quin) (4) and was monomeric with the gallium atom adopting a distorted tetrahedral geometry. Improved structural data for 1 are also reported.
