Near infra-red emission from a mer-Ru(II) complex: consequences of strong σ-donation from a neutral, flexible ligand with dual binding modes

Author affiliations

Abstract

A rare example of dual coordination modes by a novel tridentate ligand gives rise to unique fac-and mer-Ru(II/III) complexes. The mer-RuII-complex displays the farthest red-shift of a triplet metal-to-ligand charge transfer (3MLCT) emission with a tridentate ligand for a mononuclear complex. This observation is a consequence of large bite angle and strong σ-donation by the ligand, the combined effect of which helps to separate the energy of the 3MLCT and 3MC states.
