Direct synthesis of rigid ligand-bridged homo- and heterodinuclear complexes via stereoselective 1,3-dipolar coupling of mononuclear ruthenium(II) and osmium(II) precursors

摘要

A range of ligand-bridged homometallic (Ru-Ru) and heterometallic (Ru-Os) dinuclear complexes have been synthesized by the stereoselective coupling of individual performed mononuclear complexes through norbornene and epoxide functionalities attached to 1,10-phenanthroline ligating groups. The spatial orientations of the coupled chromophores were varied by control of the composition of the alicylic bridge between the two metal centers. [References: 23]
