Preferred Label : dative bond;
IUPAC definition : The coordination bond formed upon interaction between molecular species, one of which
serves as a donor and the other as an acceptor of the electron pair to be shared in
the complex formed, i e.g /i , the N B bond in H sub 3 /sub N BH sub 3 /sub . In
spite of the analogy of dative bonds with covalent bonds, in that both types imply
sharing a common electron pair between two vicinal atoms, the former are distinguished
by their significant polarity, lesser strength, and greater length. The distinctive
feature of dative bonds is that their minimum-energy rupture in the gas phase or in
inert solvent follows the heterolytic bond cleavage path.;
