Symmetric and non-symmetric bis-metallylene iron complexes, precursors of iron germanide nanoparticles

Abstract

We report herein the synthesis of symmetric and non-symmetric bis-amidinato-germylene Fe(CO)₃ complexes, as well as the preparation of the corresponding disymmetric germylene–stannylene and germylene–silylene complexes by selective displacement of a carbonyl ligand under UV-a light irradiation. The symmetric bis-germylene Fe(CO)₃ complex has been applied in the synthesis of iron germanide nanocrystals.
