Answer in brief. What are the high-spin and low-spin complexes

In the case of octahedral complexes, the question of high spin vs low spin first arises for d , since it has more than the 3 electrons to fill the non-bonding d orbitals according to ligand field theory or the stabilized d orbitals according to crystal field splitting.

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). 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.
