WebJul 24, 2024 · 1. Introduction. As early as 1942, H.C. Brown had noted that the combination of the donor and acceptor lutidine and BMe 3 failed to form a classical Lewis acid–base adduct [].Brown contrasted this combination with that of lutidine and BF 3, which forms a dative bond, and rationalized the former anomaly on the basis of steric congestion.Two … Websous le sceau de l’Université Européenne de Bretagne pour le grade de

In coordination chemistry, a coordinate covalent bond, also known as a dative bond, dipolar bond, or coordinate bond 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. This type of … See more Coordinate covalent bonding is ubiquitous.
