Heteronuclear bidentated N-H-O hydrogen bonds in the (4,4'-bipyridine)(polynitrophenols)(2) system were revealed in terms of X-ray structural analyses, ab-initio calculations, and vibrational spectra. 4,4'-Bipyridine (AA) and polynitrophenols (D) acted as Bronsted base and acid in solids, respectively. The bidentated hydrogenbonding interaction in solids was modified between [D-...+H-AA-H+...-D] and [D-H(...)AA(...)H-D] through regulating Bronsted acid-base conditions.
