Do youexpect p bonding to be important for this complex? Whatfeatures of this diagram correspond to those predicted usingcrystal field theory? What kind of bonding would VB theorypredict for d8 complexes, and how does MO theory accountfor the bonding more accurately, even qualitatively?What structural distortions would you expect to occur in the complex LnM( eta 4- butadiene) if the ligands L were made more electron releasing?
- Inorganic Chemistry (i) Define spectrochemical series (ii) Explain the difference between weak-field and strong-field ligands1) What role do the protons play in the transformation of [(SALEN)VO] to [(SALEN)Cl2]? --- Consider the number of anionic charges for all the ligands as well as the charge of the overall complex. Has the oxidation of vanadium changed in this reaction?Many transition metal complexes are said to follow the “18-electron rule,” meaning they form particularly stable complexes when the metal + ligand electrons contributing to the MOs add up to a total of 18 electrons. a. Use the full MO diagram for an octahedral metal complex with pi-acidic ligands we derived in class to justify why 18-electrons might be particularly stable. b. Use the 18-electron rule to predict which 1st row transition metal would be most likely to form an octahedral M(CO)6 (Note: there is no charge; the metal retains all its electrons.) c. Qualitatively, how would you expect the CO bond to change when it forms this complex? Would it be stronger, weaker, or the same compared to free CO? (Hint: think about what a ? −???? means and what the orbital does from the perspective of the M–CO interaction as well as the C– O interaction).
