The rutile and fluorite structures, shown here (anions are colored green), are two of the most common
Question:
(a) For CaF2 and ZnF2 use ionic radii, Ca2+ (r = 1.14 Ã…), Zn2+ (r = 0.88 Ã…), F- (r = 1.19 Ã…), to predict which compound is more likely to crystallize with the fluorite structure
and which with the rutile structure.
(b) What are the coordination numbers of the cations and anions in each of these structures?
