Probing the electronic structure of [Ru(L1)2]Z (z = 0, 1+ and 2+) (H2L1: a tridentate 2-aminophenol derivative) complexes in three ligand redox levels

Abstract

Out of neutral parent 1 (S = 0), [1OX1]¹⁺ ([Ru^III{(L^ISQ)^•−}₂]¹⁺, S = 1/2) and [1OX2]²⁺ (S = 0), [Ru^II{(L^ISQ)^•−}₂] ↔ [Ru^III{(L^AP)²⁻)}{(L^ISQ)^•−}] and [Ru^II{(L^IBQ)⁰}₂]²⁺ ↔ [Ru^III{(L^ISQ)^•−}- {(L^IBQ)⁰}]²⁺ are highly delocalized.
