Coordination bonds

Coordination bond is a type of chemical bond.

Unlike a covalent bond, the two electrons come from the same atom. They are usually more polar and shorter than covalent bonds.[1]

The bond has other names: coordinate covalent bond,[2] dipolar bond,[3] or dative bond.[1] Those names are used in coordination chemistry.

They are formed when one atom (called Lewis base) gives an electron pair to another atom (called Lewis base). This chemical reaction gives a coordination compound.
