The coordination capability of the previously reported triamidostannate [MeSi{SiMe 2 N(4‐CH 3 C 6 H 4 )} 3 SnLi(OEt 2 )] ( 1 ) as a precursor for transition metal−tin heterodimetallic complexes is presented. Whereas reaction with CH 3 I, Me 3 SiCl, or Me 3 SnCl yielded the derivatives [MeSi{SiMe 2 N(4‐CH 3 C 6 H 4 )} 3 Sn−R] (R = Me, 2 ; Me 3 Si, 3 ; Me 3 Sn, 4 ), demonstrating the nucleophilic properties of the stannate(II), its complexation to transition metal centres was achieved by halide substitution with [CuCl(PPh 3 )] 4 , [CpM(CO) 2 X] (M = Fe, X = Cl; M = Ru, X = Br), [CpM(CO) 3 Cl] (M = Mo, W) and trans (Cl)‐[RuCl 2 (bpy)(CO) 2 ] to give [MeSi{SiMe 2 N(4‐CH 3 C 6 H 4 )} 3 Sn−Cu(PPh 3 )] ( 5 ), [MeSi{SiMe 2 N(4‐CH 3 C 6 H 4 )} 3 Sn− M(CO) 2 Cp (M = Fe: 6 ; Ru: 7 )], [MeSi{SiMe 2 N(4‐CH 3 C 6 H 4 )} 3 Sn−M(CO) 2 Cp] (M = Mo: 8 ; W: 9 ) and [(MeSi{SiMe 2 N(4‐CH 3 C 6 H 4 )} 3 Sn) 2 Ru(bpy)(CO) 2 ] ( 10 ), of which 6 , 9 and 10 were characterized by X‐ray diffraction.
