In the title compound, C15H13N3O4, the pyridine and benzene rings are nearly coplanar [dihedral angle = 4.92 (12)°]. The maximum deviation from the best least-squares plane calculated for the main molecular skeleton is 0.1722 (1) Å for the carbonyl O atom. In the crystal, intermolecular O—H⋯O hydrogen bonds connect the molecules into a chain, while π–π stacking interactions between the pyridine and benzene rings [centroid–centroid distance = 3.9162 (8) Å and offset angle = 27.20°] complete a two-dimensional network.

A methanol solution (10 ml) was added to an acetone solution (10 ml) of the 2-(2-methoxyacetic acid)benzaldehyde picoloylhydrazone (0.5 mmol). After stirring at 35\ % for 2 h, crystals of the title compound were obtained by slow evaporation of the mixture at room temperature.
H atoms were placed at calculated positions (C–H = 0.93 Å and O—H = 0.82 Å) and were included in the
in the riding model approximation, with Uiso(H) = 1.2Ueq(C, N) and [Uiso(H) = 1.5Ueq(O)].Data collection: APEX2 (Bruker, 2004); cell

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

The molecular structure of (I) (Fig.1) reveals the nearly planar system; the dihedral angle between the pyridine and benzene rings is 4.923°. An intermolecular O–H···O hydrogen bond connects molecules into a chain (Table 1, Fig.2). The pyridine ring (1-x,-1/2+y,1/2-z) is parallel to the benzene ring (-x,-1/2+y,1/2-z) with a perpendicular distance of 3.3239 Å: a centroid–centroid = 3.9162 (8) Å and an offset angle = 27.197° (calculated as the angle between the line through the two centroids of the pyridine ring and the benzene ring and a normal to the pyridine plane. Thus pi–pi stacking interactions complete a two dimensional network (Fig.2).
