Heterodinuclear complexes of 4,5-diazafluorene derivatives displaying η5,κ2-[N,N] and η5,κ1-N coordination modes

Abstract

The syntheses and structures for a series of heterodinuclear complexes of 4,5-diazafluorenyl (L⁻) and 3,6-dimesityl-4,5-diazafluorenyl (L_Mes⁻) ligands are reported herein. In all these heterodinuclear complexes, the Ru^II centre is sandwiched between a pentamethylcyclopentadienyl (Cp*) ligand and the C₅ ring of L⁻ or L_Mes⁻ in a double η⁵ fashion, while the other metal (Fe^II, Co^II, Pt^II, or Cu^I) is bound to the N-donors.
