According to crystal field theory, the interaction between a transition metal and ligands arises from the attraction between the positively charged metal cation and the negative charge on the non-bonding electrons of the ligand. The theory is developed by considering energy changes of the five degenerate d-orbitals upon being surrounded by an array of point charges consisting of the ligands. …

WebCrystal Field Theory With this theory, the bonding between the central metal atom and the ligands is completely ignored. The ligands are viewed simply as mere point charges. One focuses on the valence d orbitals of the central transition metal atom and examines how the relative energies of the d orbitals change upon WebThis electrostatic model is crystal field theory (CFT). It helps to understand, interpret, and predict the colors, magnetic behavior, and some structures of coordination compounds of transition metals. CFT focuses on the nonbonding electrons on the central metal ion in coordination complexes not on the metal-ligand bonds. shut ins meaning
