WebCrystal field theory was developed by considering two compounds: manganese(II) oxide, MnO, and copper(I) chloride, CuCl. Octahedral Crystal Fields Each Mn 2+ ion in manganese(II) oxide is surrounded by six O 2- … WebThe crystal field theory (CFT) was developed for crystalline solids by the physicist Hans Bethe in 1929. The model takes into account the distance separating the positively and negatively charged ions and treats the ions simply as point charges with the attractive and repulsive interactions between them as purely electrostatic/ionic ones.
