The tris(monothiocarbamato)iron(III)complex shown to the right undergoes conversion from low to high spin state with an increase in temperature. This can be monitored by measuring magnetic moments. Predict the spin-only magnetic moment, in Bohr magnetons, that you would expect for each spin state.
An aqueous solution of cobalt (III) is diamagnetic. In the presence of excess fluoride ion, the above cobalt solution becomes paramagnetic. Use CFT arguments to give an explaination for this observation.
NiCl42- responds strongly to an external magnetic field while NiCN42- responds barely at all.
Explain how this information can be used to show that the two complexes possess differing geometries for their ligands about the metal center.
The complex Cr(H2O)63+ has high symmetry (Oh) while the complex Cu(H2O)62+ is seen to adopt lower symmetry ( D4h). Give an explaination for this observation.
Polarization in a dielectric on application of electric field is Displacement/separation of opposite charge centres.
