چکیده
In the crystal strucuture of the title compound, C(5)H(5)N(3)O, which was obtained upon recrystallization of 2-cyano-pyrimidine 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 inter-molecular N-H⋯O hydrogen bonds. Another N-H⋯O hydrogen bond between adjacent mol-ecules links them into a helical chain motif.
