Question

To the right is the structure of the complex (tetraazido) cuprate (II) [Cu (N_3)_4]^2-. The large number of azide groups makes this complex potentially very likely to explode. Determine the number and type of infra-red, Raman and inactive vibrations by using symmetry and group theory methods. Explain any choices you make. (Include only the explicitly drawn hydrogen atoms, ing for any partial credit)
