Valence Bond Theory
The valence bond theory describes the bonding in coordination compounds based on the overlapping of atomic orbitals. The valence orbitals are the outermost atomic orbitals, which are involved in chemical bonding. The atomic orbitals involved in bonding are the atomic orbitals that are not involved in bonding with other atoms.
The valence bond theory can be used to predict the molecular structure of a coordination compound. The molecular structure is the arrangement of atoms in a molecule. The valence bond theory can also be used to calculate the bond lengths and angles in a coordination compound.
Crystal Field Theory
The crystal field theory describes the bonding in coordination compounds based on the arrangement of orbitals around the metal ion. The orbitals that are oriented along the crystal field lines are the orbitals that are involved in bonding. The orbitals that are oriented perpendicular to the crystal field lines are the orbitals that are not involved in bonding.
The crystal field theory can be used to predict the physical properties of a coordination compound. The physical properties of a coordination compound, such as its melting point and boiling point, are determined by the strength of the metal-ligand bond. The crystal field theory can also be used to calculate the magnetic properties of a coordination compound
