Potassium hexachloroplatinate (IV), K2[PtCl6] adopts anti-fluorite crystal structure. The correct in — Solid State Chemistry Question

💡 Solution & Explanation

In K2[PtCl6], the PtCl6^2- ions occupy the FCC lattice points, and K+ ions occupy all the tetrahedral voids. Since this is an anti-fluorite structure, the coordination number of the PtCl6^2- ions is 8, and the coordination number of the K+ ions is 4.
