Treatment of Sn(CHR2)2 with the appropriate AgI compound in Et2O at ca. 25 °C yielded the heterobimetallic Sn−Ag (Ag−Sn‘, Ag‘−Sn) (1) and the oxidative adducts Sn(CHR2)2X2 (X = NCO (3), I (4)). 1 (Ag−Sn = 2.598(1) Å) and 3 have been characterized by X-ray studies, and 1 and 2 provide the first examples of 119Sn−109Ag and 119Sn−107Ag coupling in their 119Sn{1H} NMR spectra (R = SiMe3).
