Abstract

Valencies get remix: A unique kind of electronic structure (Mn+0.5)(μ-L.-)(Mn+0.5) which was previously discussed only for metal-ligand charge-transfer (MLCT) excited states is established structurally and by quantum chemical analysis for both rac (see picture) and meso isomers of [(μ-abpy){Ru(acac)2}2] (abpy=2,2'-azobispyridine, acac-=acetylacetonate).
