A unique kind of electronic structure (Mn+0.5)(m-L.bul.-)(Mn+0.5) which was previously discussed only for metal-ligand charge-transfer (MLCT) excited states is established structurally and by quantum chem. anal. for both rac and meso isomers of (m-abpy)Ru(acac)22 (abpy = 2,2'-azobispyridine, acac- = acetylacetonate). on SciFinder(R)
