1. For each of the following, draw the structure, determine the point group, find the LFSE (in terms of Dq and P), estimate the magnetic moment in terms of Bohr-Magnetons, predict the stability based on the EAN rule, and indicate if the complex will be Jahn-Teller active. If the complex is Jahn-Teller active, indicate the nature of the distortion. Indicate which bonding theory is the better choice for each species.
a. diaquadichlorocobalt(II)
b. cis-diaquadichlorocopper(II)
c. decacarbonyldimanganese(0) (deca = 10)
d. bis-(η6-benzene)chromium(0)
e. cis-tetracyanodifluoroferrate(II) ion
2. For each of the following, give the systematic name, determine the point group, find the LFSE (in terms of Dq and P), estimate the magnetic moment in terms of Bohr-Magnetons, predict the stability based on the EAN rule, and indicate if the complex will be Jahn-Teller active. If the complex is Jahn-Teller active, indicate the nature of the distortion. Indicate which bonding theory is the better choice for each species.
a. trans-Ru(bpy)2Cl2
b. cis-Ni(NH3)4Br2 (ignore H atoms when determining the point group)
c. fac-Cr(CH3NH2)3F3 (ignore H atoms when determining the point group)
d. Mo(CO)6
e. Mn(η5-cp)(CO)3
