B(OH)2 versus OH in supramolecular synthesis: molecular complexes of 4-hydroxyphenylboronic acid with aza-donor compounds

–B(OH)2 moiety forms interactions with aza-donor compounds as much as –OH does, as derived from the supramolecular assemblies of 4-hydroxyphenylboronic acid with aza-donor compounds demonstrating for the first time, a comparative study of –B(OH)2 versus –OH.
