Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>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.</p> </abstract>
