What is Coordinate Covalent Bond?
A coordinate covalent bond (dative bond) is a covalent bond in which both electrons in the shared pair are donated by the same atom, called the donor. The atom accepting the electron pair is the acceptor. Once formed, a coordinate bond is indistinguishable from an ordinary covalent bond. It is important in the formation of complex ions and Lewis acid-base adducts.

Frequently Asked Questions
A coordinate covalent bond (dative bond) is a covalent bond in which both electrons in the shared pair are donated by the same atom, called the donor. The atom accepting the electron pair is the acceptor. Once formed, a coordinate bond is indistinguishable from an ordinary covalent bond. It is important in the formation of complex ions and Lewis acid-base adducts.
Coordinate bonds are central to coordination chemistry (metal-ligand bonding), Lewis acid-base chemistry (BF₃:NH₃), biochemistry (metal-enzyme active sites), and in adducts of boranes. They explain the bonding in complex ions and organometallic compounds.
Compounds formed via coordinate bonds (BF₃ complexes, metal-cyanide complexes) vary widely in hazard. BF₃ etherate releases corrosive BF₃ gas on hydrolysis. Coordinate complexes of highly toxic ligands (CO, CN⁻) must be handled with extreme care.
