Bis(benzene) chromium can be considered as a hexagonal prism. With drawings show how the atomic positions change as you repeatedly do an S6 rotation about the principle axis, until you return to the original orientation (Hint: you can ignore the hydrogens on the benzenes). Which symmetry operations generated by the S6 axis are unique, and which ones duplicate other symmetry operations? List all symmetry elements and symmetry operations for this molecule. With drawings, indicate the locations of all rotation axes and mirror planes. What is the point group of the molecule?
