TiCl 4 reacts quantitatively with Cl 2 Si(NHSiMe 3 ) 2 in n ‐pentane under evolution of Me 3 SiCl yielding [μ‐ClTiCl 2 N(SiMe 3 )‐SiCl 2 NH 2 ] 2 ( 1 ), which is obtained as a yellow, crystalline solid forming small intergrown needles, that rapidly hydrolyse. The product 1 shows a thermal stability up to 80?C. The molecular structure of 1 has been solved by X‐ray powder diffraction methods and it could be confirmed by single‐crystal X‐ray structure determination at ‐70 ?C. Accordingly, in the solid 1 is a dimer ([μ‐ClTiCl 2 N(SiMe 3 )SiCl 2 NH 2 ] 2 , P 2 1 / n (no. 14), Z = 2, a = 1504.89(6), b = 1296.33(6), c = 710.90(4) pm, and β = 91.276(2)?).
