| Popis: | Valencies get remix: A unique kind of electronic structure (M n+0.5 )(μ-L. - )(M n+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). |
