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)
