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 Brønsted base and acid in solids, respectively. The bidentated hydrogen-bonding interaction in solids was modified between [D-⋯+H-AA-H+⋯-D] and [D-H⋯AA⋯H-D] through regulating Brønsted acid-base conditions.
