Crystal Field Theory<\/strong><\/p>\n\n\n\n

Crystal field theory established in 1929 explains the interaction of the metal ion and the ligand as a pure electrostatic reaction , where the ligands are considered as the point charges in vicinity of the atomic orbitals<\/a> of the central atom. <\/p>\n\n\n\n

The extension and development of the crystal field theory takes into account the partial covalent nature of bonds that exists between the ligand and the metal atom.<\/p>\n\n\n\n

It is mainly through the application of molecular orbital theory. Crystal field theory often termed as ligand field theory.<\/em> The theory points out anions as point charges and neutral molecules as dipoles<\/a>.<\/p>\n\n\n\n

Therefore the theory was proposed as it provided description on the metal-ligand bond<\/p>\n\n\n\n

As an ionic bond arises only from the electrostatic interactions between the metal ions and ligands. Crystal field theory considers anions as point charges and neutral molecules as dipoles.<\/p>\n\n\n\n

When there exists no bond of the transition metals to any ligand, their d orbitals are degenerate, meaning they have the same energy. <\/p>\n\n\n\n

When bonding with other ligands takes place, as a result of different symmetries<\/p>\n\n\n\n

Therefore the d orbitals and the inductive effect of the ligands on the electrons, the d orbitals split apart and dont break.<\/p>\n\n\n\n

Features of Crystal Field Theory<\/h2>\n\n\n\n

\u00b7The Crystal field theory (CFT) is a model for the bonding interaction between transition metals and ligands.<\/p>\n\n\n\n

In other words it describes the effect of attraction in cations and ligands.<\/p>\n\n\n\n

The attraction between the positive charge of the metal cation and negative charge on the non-bonding electrons of a ligand. <\/p>\n\n\n\n

Therefore, When the ligand approaches the central metal ion the dangerously of electronic orbital states, usually d or f orbitals, breaks due to the statistic electric field by a surrounding charge distribution. <\/p>\n\n\n\n

In other words, CFT successfully accounts for some magnetic properties, colours, hydration energies of transition metal complexes, <\/p>\n\n\n\n

CFT does not help to describe bonding ,The net change in crystal energy resulting from the orientation of d orbitals<\/em> of a transition metal cation inside a coordinating group of anions also called ligands.<\/p>\n\n\n\n

However an important factor of transition is that they have the ability to form complexes, the complex form may be a central metal ion or an atom surrounded by many ligands. <\/p>\n\n\n\n

The interaction that occur between these ligands with the central metal atom or ion is subject to the theory.<\/p>\n\n\n\n
