Abstract

Reduction of hexaazatrinaphthylene (HAN) and its hexamethyl derivative with [Cp*₂Sm(THF)₂] or [Cp*₂Yb(OEt₂)] produces [(Cp*₂Ln)₃(R₆HAN)] (Ln = Sm, Yb; R = H, Me), where the heterocyclic ligand forms as a trianion. The magnetism and electronic structure of these compounds reflect unusual multiconfigurational character within the reduced ligand but not the lanthanide ions.
