Two independent mol-ecules are present in the asymmetric unit of the title compound, C(12)H(10)N(2)O, in which the 3-hy-droxy-benzaldehyde and the pyridin-3-amine units are almost planar [r.m.s. deviations of 0.0236 and 0.0116Å, respectively, in one mol-ecule and 0.0245 and 0.0162Å, respectively, in the other] and are oriented at dihedral angles of 7.21 (7) and 14.77 (7)°. In the crystal, mol-ecules of the same type form inversion dimers via pairs of O-H⋯N hydrogen bonds, forming R(2) (2)(20) ring motifs. There exist π-π inter-actions between the benzene and pyridine rings of molecules of the same type with centroid-centroid distances of 3.7127 (10) and 3.8439 (10) Å.
标题化合物C(12)H(10)N(2)O的不对称单元中存在两个独立分子，其中3-羟基苯甲醛和吡啶-3-胺单元几乎呈平面状[在一个分子中，均方根偏差分别为0.0236和0.0116Å，在另一个分子中分别为0.0245和0.0162Å]，且二者以7.21(7)°和14.77(7)°的二面角取向。在晶体中，同种类型的分子通过O-H⋯N氢键对形成反演二聚体，形成R(2)(2)(20)环 motif。同种类型分子的苯环和吡啶环之间存在π-π相互作用，质心间距为3.7127(10)和3.8439(10)Å。
