Question

What is an antifluorite structure??

Answer 1

The fluorite structure can be generated by starting with a FCC lattice of cations (A) and filling all of the tetrahedral holes with anions (X). The antifluorite structure is identical except that the anion and cation coordinations are reversed.

Answer 2

Answer:

Antifluorite is a mineral with a crystal structure identical with that of fluorite but with the positions of the cations and anions reversed (Figure 6.11D. ... The same crystal structure is found in numerous ionic compounds with formula AB2, such as ceria (CeO2), zirconia (cubic ZrO2), uranium dioxide (UO2).
