description In the crystal strucuture of the title compound, C(5)H(5)N(3)O, which was obtained upon recrystallization of 2-cyano­pyrimidine from aqueous sodium hydroxide, the amide group is twisted with respect to the aromatic ring by 24.9 (1)°. π–π stacking is observed between partially overlapped rings at a face-to-face separation of 3.439 (6) Å. The structure features a centrosymmetric pair of inter­molecular N—H⋯O hydrogen bonds. Another N—H⋯O hydrogen bond between adjacent mol­ecules links them into a helical chain motif.
