WebSep 18, 2024 · The CFSE is usually greater for octahedral than tetrahedral complexes. Remember that Δ o is bigger than Δ tet (in fact, Δ tet is approximately 4/9 Δ o ). If we make the assumption that Δ tet = 4/9 Δ o, we can calculate the difference in stabilization energy between octahedral and tetrahedral geometries by referencing everything in terms ...
