Coordination bonds
Coordination bond is a type of chemical bond.
The bond has other names: coordinate covalent bond,[1] dipolar bond,[2] or dative bond.[3] 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.
