Antifluorite structure is derived from fluorite structure by inter-changing the positions of positive and negative ions in the lattice. For example, CaF

has fluorite structure. The Ca

ions are arranged in ccp arrangement and the F

−

ions occupy all the tetrahderal holes. Li

O has antifluorite structure. The O

2−

ions are arranged in ccp arrangement and the Li

ions occupy all the tetrahederal holes.

antifluorite structure :

❤

The antifluorite structure has ccplfcc anions with cations in all (T+ and T-) tetrahedral sites. The difference between antifluorite and fluorite is that anti- fluorite refers to an anion array with tetrahedral cations, whereas fluorite has the inverse arrangement with a ccp cation array and tetrahedral anions.
