This definitive reference consolidates present wisdom on dihydrogen bonding, emphasizing its function in organizing interactions in numerous chemical reactions and molecular aggregations. After an outline, it analyzes the variations among dihydrogen bonds, classical hydrogen bonds, and covalent bonds. It describes dihydrogen bonds as intermediates in intramolecular and intermolecular proton move reactions. It describes dihydrogen bonding within the solid-state, the fuel section, and in resolution. this is often the ideal reference for actual chemists, biochemists, biophysicists, and chemical engineers.

As shown, some combinations of pK values (when both AH and BH components have pK values higher than 7) lead to a situation in which the proton-hole-transfer pathway can become more energetically favorable [30]. 2. 6) where X is a carbon atom and B is isocyanides (R–N≡C:), carbenes (C:), carbanions (C− ), or π-electronic systems. Among π-electronic systems acting as proton acceptors, the gold ethyne and benzene complexes are best known. Some of them have been characterized by NONCONVENTIONAL HYDROGEN BONDS OF HYDROGEN-BONDED SYSTEM 21 x-ray crystallography: for example, the T-shaped Cl3 C–H· · · π(C≡C) hydrogenbonded system [3].
