Chapter 4, Problem 4.41P

Determine the point groups of the following:
a. The cluster anion ${\left[\text{Re}\left(\mu \text{3}-\text{S}\right){\left(\mu -\text{S}\right)}_{\text{3}}{\text{Br}}_{\text{9}}\right]}^{\text{2}}$ (Reference: H. Sakamoto, Y. Watanabe, T. Sato,
Inorg. Chem., 2006, 45, 4578.)

b. The cluster anion ${\left[\text{Fe}@\text{Ga1}0\right]}^{\text{3}-}$ (Reference: B. Zhou, M. S. Denning, D. L. Kays, J. M. Goicoechea, J. Am. Chem. Soc., 2009, 131, 2802).

c. The “corner” and “square” structures: (Reference: W. H. Otto, M. H. Keefe, K. E. Splan, J. T. Hupp, C. K. Larive, Inorg. Chem. 2002, 41, 6172.)

d. The ${\left[{\text{Bi}}_{\text{7}}{\text{l}}_{\text{24}}\right]}^{\text{3}-}$ ion. (Reference: K.Y. Monakhov, C. Gourlaouen, R. Pattacini, P. Braunstein,
lnorg. Chem., 2012, 51, 1562. This reference also has alternative depictions of this
structure.
