Abstract

In the title compound, C6H7N3O, the amide group is rotated such that the carbonyl O atom is syn to the pyridine N atom, with an O—C—C—C torsion angle of −23.55 (18)°. The crystal packing involves four hydrogen bonds of the types N—H⋯N and N—H⋯O. Two separate centrosymmetric rings are formed using N—H⋯N and N—H⋯O hydrogen bonds that result in a ribbon of 6-aminonicotinamide molecules, joined by the amide and amine functional groups. The remaining two hydrogen bonds are used to generate a three-dimensional packing arrangement.
