fluorite structure

Chemistry

A type of ionic crystal structure in which the cations have an expanded face-centred cubic arrangement with the anions occupying both types of tetrahedral hole. The cations have a coordination number of 8 and the anions have a coordination number of 4. Examples of compounds with this structure are CaF₂, BaCl₂, and PbO₂.
The antifluorite structure is the opposite arrangement, with anions in the f.c.c. array with coordination number 8 and cations in the tetrahedral holes with coordination number 4. Examples of the antifluorite structure are K₂O, Li₂O, Na₂O, K₂S, and Na₂S.
