Lanthanide(II) Complexes of a Dual Functional Tris(2‐pyridyl)stannate Derivative

Abstract

Dual functionality: The reaction of [LiSn(2-C5H3N-5-Me)3(thf)] with [Ln(η5-C5Me5)2] derivatives results in formation of the first LnII sandwich complexes comprising the anionic tris(pyridyl)-stannate as a κ3N-coordinating ligand and featuring “naked” anionic SnII centers, which can be used for subsequent κ1Sn-metal coordination (example seen here; brown=Eu, red=Sn, yellow=Li).
