Complexes: - Copper(II)-acac - Bis-(3-chloro-2,4-pentanediono)-copper(II) (copper chloro derivative) - Aluminium(III)-acac - Aluminium(III)-acacc diazo derivative Q. Form the bromoination of Copper(II)-acac and the diazotisation of Aluminium(III)-acac to their derivatives, explain whether there is evidence of substitution in the electrophilic reactions and what implications arise from this (evidence is encouraged!)

State the point group symmetry for Mn(acac), [Co(bpy)3](PF6)2, and [Cu(bpy)2](PF6)2 (ignoring the counter anion structure) and illustrate (using an energy level diagram like that used in the lecture) the appropriate valence d electronic configuration (e.g. t2gxegy for Oh and ex t2y for Td) for all investigated metal ions. This schematic of the crystal field splitting diagram for each complex should illustrate the correct distribution of electrons between each orbital level in each case inclusive of any predicted Jahn-Teller distortion.

In relation to M(acac)3 complexes, assuming they contain an octahedrally coordinated M3+ ion: Draw the ligand field orbital diagrams for Co(III), Fe(III), Mn(III), and Cr(III) to derive the possible electron configurations for the metal complexes. State the number of unpaired spins each configuration has. Which is the correct d-electron configuration for each complex? Which complexes are "high spin" and which are "low spin"? Thanks so much! I will give immediate upvotes!

For an Mn based ferrite, MnFe2O4, the magnetic moment comes from Mn. Given that the saturation magnetization of MnFe2O4 is 5.6×105 A/m, the atomic weight is 230.64 g/mol and density is 5.0 g/cm3. Calculate the number of Bohr magnetons per Mn2+ ion.
