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.

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.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
