Treatment of Sn(CHR₂)₂ with theappropriateAg^I compound in Et₂O at ca. 25 C yielded theheterobimetallic Sn-Ag complexes[(Ag(SCN){Sn(CHR₂)₂}(thf))₂] (Ag-Sn', Ag'-Sn) (1) and(1/n)[(Ag(CN){Sn(CHR₂)₂})_n](2) and the oxidative adductsSn(CHR₂)₂X₂(X = NCO (3), I (4)). 1(Ag-Sn = 2.598(1) Å) and 3have been characterized by X-ray studies, and 1 and2provide the first examples of¹¹⁹Sn-¹⁰⁹Ag and¹¹⁹Sn-¹⁰⁷Ag coupling in their¹¹⁹Sn{¹H} NMR spectra (R=SiMe₃).
