caption_attribution_description: This is a POV ray drawing of a small section of the lattice of an imaginary perovskite. The red atoms are oxygen anions while the the green atom represents the larger cation, and the blue central atom the smaller cation, typically with a higher oxidization state. I created this file by writing a XYZ file using a spreadsheet after reading cotton and wilkinson, this was edited using the text editor of ORTEP. ORTEP was used to write the pov file, then POVray was used to draw it.
context_page_description: A perovskite is any material with the same type of crystal structure as calcium titanium oxide, known as the perovskite structure. Perovskites take their name from the mineral, which was first discovered in the Ural mountains of Russia by Gustav Rose in 1839 and is named after Russian mineralogist L. A. Perovski. The general chemical formula for perovskite compounds is ABX₃, where 'A' and 'B' are two cations of very different sizes, and X is an anion that bonds to both. The 'A' atoms are larger than the 'B' atoms. The ideal cubic structure has the B cation in 6-fold coordination, surrounded by an octahedron of anions, and the A cation in 12-fold cuboctahedral coordination.
  Natural compounds with this structure are perovskite, loparite, and the silicate perovskite bridgmanite.

caption: Structure of a perovskite with general chemical formula ABX3. The red spheres are X atoms (usually oxygens), the blue spheres are B atoms (a smaller metal cation, such as Ti4+), and the green spheres are the A atoms (a larger metal cation, such as Ca2+). Pictured is the undistorted cubic structure; the symmetry is lowered to orthorhombic, tetragonal or trigonal in many perovskites.[1]
