Antiperovskite

Antiperovskite refers to a class of materials that have a specific crystal structure characterized by the arrangement of atoms in a particular way. The name "antiperovskite" is derived from the perovskite structure, but with a different arrangement of cations and anions. In a typical perovskite structure, which has the general formula ABX₃, "A" and "B" are cations and "X" is an anion.
