By in situ lithiation of the trifunctional amines H3CC(CH2NHSiMe3)3, PhC(CH2NHSiMe3)3, and HC{SiMe2NH(p‐Tolyl)}3 and subsequent reaction with SnCl2 the corresponding triamidostannates were obtained. These were coupled with CpM(CO)2Cl (M Fe, Ru) to yield the M—Sn‐bonded heterobimetallics 9–14 of which H3CC(CH2NSiMe3)3SnFe(CO)2Cp (9) was characterized by a single‐crystal X‐ray structure analysis. Of the in situ‐generated amidostannates only [HC{SiMe2N(p‐Tolyl)}3Sn][Li(THF)3] (8) could be isolated as a uniform product and characterized analytically and spectroscopically.
