Herein, we report the syntheses of silicon‐ and tin‐containing open‐chain and eight‐membered‐ring compounds Me2Si(CH2SnMe2X)2(2, X=Me;3, X=Cl;4, X=F), CH2(SnMe2CH2I)2(7), CH2(SnMe2CH2Cl)2(8),cyclo‐Me2Sn(CH2SnMe2CH2)2SiMe2(6),cyclo‐(Me2SnCH2)4(9),cyclo‐Me(2−n)XnSn(CH2SiMe2CH2)2SnXnMe(2−n)(5,n=0;10,n=1,X=Cl;11,n=1,X=F;12,n=2,X=Cl), and the chloride and fluoride complexes NEt4[cyclo‐ Me(Cl)Sn(CH2SiMe2CH2)2Sn(Cl)Me⋅F] (13), PPh4[cyclo‐Me(Cl)Sn(CH2SiMe2CH2)2Sn(Cl)Me⋅Cl] (14), NEt4[cyclo‐Me(F)Sn(CH2SiMe2CH2)2Sn(F)Me⋅F] (15), [NEt4]2[cyclo‐Cl2Sn(CH2SiMe2CH2)2SnCl2⋅2 Cl] (16), M[Me2Si(CH2Sn(Cl)Me2)2⋅Cl] (17 a, M=PPh4;17 b, M=NEt4), NEt4[Me2Si(CH2Sn(Cl)Me2)2⋅F] (18), NEt4[Me2Si(CH2Sn(F)Me2)2⋅F] (19), and PPh4[Me2Si(CH2Sn(Cl)Me2)2⋅Br] (20). The compounds were characterised by electrospray mass‐spectrometric, IR and1H,13C,19F,29Si, and119Sn NMR spectroscopic analysis, and, except for15and18, single‐crystal X‐ray diffraction studies.
