About Fe (III) and Fe (II) coordination complexes

WebSep 7, 2024 · Theoretically, you cannot predict a priori whether a compound is high- or low-spin. For some reason, a lot of people seem to think that it depends only on the ligand and that it is possible to unambiguously use the position of the ligand in the spectrochemical series to figure out whether a complex is high- or low-spin. WebBei d 3, d 4, d 5, d 6 wären beide Konfigurationen "low spin" und "high spin" zu erwarten – wegen der geringen Feldaufspaltung existieren jedoch nur "high spin"-Komplexe (Eine Ausnahme stellt beispielsweise Tetrakis(1-norbornyl)cobalt(IV) dar, dessen Norbornyl-Liganden eine hinreichende Aufspaltung bewirken).
