Question

For the following complexes: i) give the formal oxidation state of the metal i) the d" count for the metal ions (e.g. Fe -> d6) ili) sketch the compound iv) give its point group v) provide a d-orbital splitting diagram indicating the correct symbols for the point group vi) Indicate if you would predict a Jahn-Teller distortion (no need to distort to splitting diagram) vii) Indicate whether you would predict any MLCT or LMCT transitions viii) Predict the intensity of any d-d transitions, describing them as weak ( 100) and explain which selection rules apply.
