摘要：

The metalation of Ph3SnH with nBuLi in the presence of the tridentate amine ligand N,N,N',N'',N''-pentamethyldiethylenetriamine (PMDETA) provides the title compound. Crystal structure analysis shows this to be monomeric in the solid state and to contain a direct Sn-Li bond. This structure is preserved in solution, as demonstrated in low-temperature Li-7 NMR studies.
