24. Transition Metals and Coordination Compounds
Strong-Field vs Weak-Field Ligands
The hypothetical complex [A(H2O)6]2+ has a d-d transition that produces an absorption maximum at a wavelength of about 550 nm.
1. What is the value of Δ for [A(H2O)6]2+ in kJ/mol?
2. How would the magnitude of ∆ change if the H2O ligands in [A(H2O)6]2+ were replaced with NO2−?
