Why are different colour observed in octahedral and tetrahedral complexes for same metal & same ligands?

Text Solution

Verified by Experts

`Delta_(t)=((4)/(9))Delta_(o)`. So `Delta_(t)` is smaller than `Delta_(o)`. Hence for `d-d` transition, higher wavelength (lower energy) is absorbed by tetrahedral complexes than by octahedral complexes consisting of the same metal and ligands.
