dipolar bond

However, this is not always the case, leading to dative or dipolar bonds).

This electronic structure has an electric dipole, hence the name dipolar bond.

Coordination refers to the "coordinate covalent bonds" (dipolar bonds) between the ligands and the central atom.

This is achieved by providing lone pairs of the ligand into empty orbitals of the metal atom and forming dipolar bonds.

A dipolar bond, also known as a dative covalent bond or coordinate bond is a kind of 2-center, 2-electron covalent bond in which the two electrons derive from the same atom.

Since four of the shared electrons come from the oxygen atom and only two from carbon, one bonding orbital is occupied by two electrons from oxygen, forming a dative or dipolar bond.

The term dipolar bond is used in organic chemistry for compounds such as amine oxides for which the electronic structure can be described in terms of the basic amine donating two electrons to an oxygen atom.
