3. Transition metals of the periodic table are known to adopt either a tetrahedral or square planar configuration when it has a coordination number of 4. Consider the inorganic complex ZrI4. a) Draw the structure, determine all symmetry elements and operations, and assign point group classification of Zr14 if it is tetrahedral, and square planar. (10 pts) b) If Zrl is tetrahedral, how many IR absorption peaks is expected given its point group classification? (2 pts) c) If Zrl4 is square planar, how many IR absorption peaks is expected given its point group (2 pts) classification? d) The IR spectrum of gaseous Zrl4 shows absorption peaks at 55 cm-1 and 245 cm-1. This data is consistent with what shape of ZrI4. (2 pts)

Determine the symmetry point groups of the mer- and fac- isomers of the complex [Re(CO)3(NCMe)3] and deduce the irreducible symmetry representations generated by the three stretching vibrations of the C triple bond to N ligands in each of the isomers. [Regard NCMe as a linear ligand.] Also for each isomer discussed, state with reasoning which vibrations are IR active, and which are Raman active and how many bands will be observable in IR and Raman spectra. How can you distinguish the two isomers using their vibrational spectra?
