| Abstract: | The coordination chemistry of cyclic stannylene‐based intramolecular Lewis pairs is presented. The P→Sn adducts were treated with Ni(COD)2] and Pd(PCy3)2] (COD=1,5‐cyclooctadiene, PCy3=tricyclohexylphosphine). In the isolated coordination compounds the stannylene moiety acts either as an acceptor or a donor ligand. Examples of a dynamic switch between these two coordination modes of the P?Sn ligand are illustrated and the structures in the solid state together with heteronuclear NMR spectroscopic findings are discussed. In the case of a Ni0 complex, 119Sn Mössbauer spectroscopy of the uncoordinated and coordinated phosphastannirane ligand is presented. |
