The metalation of Ph 3 SnH with n BuLi 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 SnLi bond. This structure is preserved in solution, as demonstrated in low‐temperature 7 Li NMR studies.
