Consider the coordination complex with the formula: [Fe(NH3)4(NO2)2]Br a. Can this complex have isomers? If so state which types? Explain your decisions about isomers based on the number and type of each ligand. Hint: what atoms of NO2 - ion can bind the metal ion? Also do you have ‘looping’ ligands? Isomer types include: geometric (cis-trans), linkage, optical, and coordination. b. Draw the crystal field diagram (of d orbital energies) for this complex. State the number of unpaired electrons on the Fe ion. Label the potential energy axis and the 2 orbital levels on your diagram. c. Predict the color of this complex. Explain your answer based on the field strength of the two types of ligands in the complex, using field strength listing below and the color wheel provided on the equations page. d. Will this complex be paramagnetic or diamagnetic? Explain your decision briefly based on the number of unpaired electrons on the metal ion in the complex.
