Web1 de jun. de 2009 · A number of important chemical and biochemical systems where strong H-bonds play an important functional role are surveyed, such as enzymatic … WebIn comparison with hydrogen bonds, the utility of other directional noncovalent interactions, of which halogen bonds are the main representative, is more limited. (26−30) Here, we focus on imparting directionality to ionic bonds in an attempt to provide a distinct directional noncovalent interaction for the three-dimensional structuring of matter.
