CuI, CsI, and NaI each adopt a different type of structure. The three different structures are those

Question:

CuI, CsI, and NaI each adopt a different type of structure. The three different structures are those shown in Figure 12.26.
(a) Use ionic radii, Cs+ (r = 1.81 Å), Na+ (r = 1.16 Å), Cu+ (r = 0.74 Å), and 1- (r = 2.06 Å), to predict which compound will crystallize with which structure.
(b) What is the coordination number of iodide in each of these structures?
