Perovskite (structure)

Structure of a perovskite with general chemical formula ABX 3.The red spheres are X atoms (usually oxygens), the blue spheres are B atoms (a smaller metal cation, such as Ti 4+), and the green spheres are the A atoms (a larger metal cation, such as Ca 2+).Pictured is the undistorted cubic structure; the symmetry is lowered to orthorhombic, tetragonal or trigonal in many perovskites.
