 Perovskite (structure)

An ABX3 connectivity of corner-sharing BX6 octahedra with A ions in the larger cavities.

Perovskite refers to a specific class of materials that have a characteristic crystal structure named after the mineral perovskite (CaTiO3), which was first discovered in the Ural Mountains in Russia. The general formula for perovskite-structured materials can be expressed as ABX3, where: - A is a cation (a positively charged ion) that occupies the larger dodecahedral sites.
