The structure of the organic–inorganic hybrid material 4-aminopyridinium nitrate, C5H7N2+·NO3−, exhibits classical and bifurcated strong N—HO hydrogen-bonding interactions, as well as weaker C—HO interactions. Organic 4-aminopyridinium cations and inorganic nitrate anions interact to form a one-dimensional hydrogen-bonded ribbon in the a direction. Neighbouring ribbons interact to form two-dimensional corrugated hydrogen-bonded sheets parallel to the ac plane.
