Coordinate covalent bond

In coordination chemistry, a coordinate covalent bond,^[1] also known as a dative bond,^[2] dipolar bond,^[1] or coordinate bond^[3] is a kind of two-center, two-electron covalent bond in which the two electrons derive from the same atom. The bonding of metal ions to ligands involves this kind of interaction.^[4] This type of interaction is central to Lewis acid–base theory.

Coordinate bonds are commonly found in coordination compounds.^[5]
