The cyclo-tristannazanes [Me2Sn-N(R)](3) (with R = Me, Pr-n,Pr-i,Bu-i) have been prepared from Me2SnCl2 and LiN(H)R in a 1:2 molar ratio. With MMe3 (M = Al, Ga, In) they form the dimeric dimethylmetal trimethylstannyl(alkyl)amides 1[Me2M-N(R)SnMe3](2) in good yields. The mass, NMR (H-1, C-13, Sn-119), and vibrational spectra are discussed and compared with the spectra of the tristannazanes. Thermolysis of the gallium amidocompounds splits SnMe4 to form methylgallium imido derivatives with cage structures. The crystal structures of selected stannylamido complexes have been determined by X-ray structure analysis.
