  Bis(N-trimethylsilylamino)plumbylenes 1 [Me3Si(R)N](2)Pb with R = Bu-t (a), Me3Si (b), 9-(9-borabicyclo[3.3.1]nonyl) (c)} react smoothly with an excess of TiCl4 to give PbCl2 and N-trimethylsilylaminotitanium trichlorides 3 a-c. In contrast, the analoguous reaction of the corresponding stannylenes 2a-c leads to mixtures containing unidentified Ti-III compounds, the amides 3a or 3b, bis[bis(trimethylsilyl)amino]titanium dichloride 4b and bis(amino)tin dichlorides 5 a-c. The crystal structure of 3a was determined by X-ray structural analysis. Compound 3a is a dimer in the solid state with distorted trigonal pyramidal surroundings of the titanium atoms. Each titanium atom bears two mu(2)-Cl ligands which are in axial (d(Ti-Cl) = 250.7(1) pm) and equatorial positions (dn(Ti-Cl) = 247.0(1) pm) and two terminal chloro ligands, one in axial (d(Ti-Cl) = 228.0(1) pm) and one in equatorial position (da(Ti-Cl) = 221.1(1) pm). The equatorial Ti-N bonds are short (183.8(2) pm).
