WebThe current model of bonding in coordination complexes developed gradually between 1930-1950. In its initial stages, the model was a purely electrostatic one known as crystal field theory which treats the ligand ions as simple point charges that interact with the five atomic d orbitals of the central ion. It is this theory which we describe below. http://home.iitk.ac.in/~madhavr/CHM102/Notes_on_Coordination_Compounds.pdf iowa code stop sign
