WebCrystal Field theory describes the bonding of complex ions of transition metals in terms of electrostatic forces. In a complex ion two types of electrostatic interactions are operative: 1) Attraction between the positively charged metal ion and negatively charged ligand or the negatively charged end of a polar ligand. WebThe crystal structure determines the way the atoms interact with each other. Crystal field theory is used to understand the way the atoms in a crystal interact. It is based on the idea that crystals are made up of tiny particles called "atoms." Each atom is surrounded by a tiny "crystal field." The crystal field affects the way the atom behaves.
