, and [SnBu
2(Asc)], respectively. The new compounds were studied in the solid state by CP/MAS
13C NMR and IR spectroscopy, and in aqueous solution by
1H,
13C,
205Tl, and
119Sn NMR spectroscopy. The thallium compound behaves as a salt. In the tin derivatives, the metal appears to interact with the (Asc)
2− anion through the O(1), O(2), and O(3) atoms of the lactone ring. Other possible weak interactions of the tin complexes in the solid state are also discussed. |
