Question

Which of the following compounds have an antifluorite structure? (A) K 2 O (B) BaF 2 (C) CuBr (D) TiI

Tardigrade Admin · Accepted Answer

K 2 O has an antifluorite structure. O 2- ions forms ccp, i.e., these are present at the corners and at the centres of all six faces. K + ions occupy all the tetrahedral voids.
