Question

1. For the following complexes: i) give the formal oxidation state of the metal ii) the d count for the metal ions (e.g. Fe → d). iii) sketch the compound iv) give its point group v) provide a qualitative o-only d-orbital splitting diagram indicating the correct symbols for the point group (i.e. a10) vi) Indicate if you would predict a Jahn-Teller distortion (no need to distort to splitting diagram) vii) Calculate the spin-only value of Weft, and predict which species might exhibit deviation from the spin-only value based on the deviations discussed in class (angular momentum, spin-orbit coupling, J-T distortion, electron delocalization) viii) Indicate whether you would predict any MLCT or LMCT transitions in the visible region ix) Predict the intensity of any d-d transitions, describing them as weak (€ < 1), moderate (E = 1 - 100), or strong (€ > 100) and explain which selection rules apply. Ligands: ppy = 2-phenylpyridine (chelate), bipy = 2,2-bipyridine) a. Ti(CN):3- b. Ni(edta)2-(use On) c. MnO4 >d. Co(bipy)32 (low spin) ICL2

just part d please

Answer 1

Сосыр),t- bipy is neutral bidentate ligand. so ocidation state of metal will be уғ 3(6) 2+2 а) х = t2 Гcote] со a 3d 742 (Ь co**= ad? уд° 0 biba

- It contain E, C & Cz & so point group will be D3 & splitting will be as - - - try to I tiu of beli ya dig, g ty V av tiu 9 Ligand Metal Cot² = ď ( cowspin) (GiByh = 2x6 =12 Total é 12+7219
