Synthesis and structure of the first non ‘ate’ heteroleptic lanthanoid complexes bearing monoanionic 2-amidopyridine ligands

Abstract

The synthetic utility of the polymeric alkali metal N-silylated-2-amidopyridine species [{Na(AMPTMS)(THF)_0.5}_n] (AMPTMS = 2-(trimethylsilylamido)-6-methylpyridine) toward the first non ‘ate’ heteroleptic lanthanoid complexes bearing monoanionic 2-amidopyridine ligands has been investigated. The preliminary results of this study are presented herein. These comprise the preparation and structural characterisation of dimeric [{Nd(AMPTMS)₂(THF)(μ-Cl)}₂] and monomeric [TbCp*₂(AMPTMS)] (Cp* = C₅Me₅), the latter being the first terbium Cp* compound structurally characterised.
