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 states that the resulting field splits the degenerate atomic 3d orbitals into molecular e g and t 2g orbitals.

WebAccording to crystal field theory, the five 3d orbitals of first series transition metal ions are split into two energy levels when the cation is surrounded by ligands (e.g. oxygen anions). In octahedral coordination, three of the 3d orbitals (the taP. set) are stabilized relative to the other two (the e, set), the energy separation (crystal ... 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.

WebThe Crystal Field Theory (CFT) is a model for the bonding interaction between transition metals and ligands.
