In the title compound, C(6)H(7)N(3)O, 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.
