In the title compound, C14H13N3O3, the dihedral angle between the pyridine and benzene rings is 15.17 (18)°. The torsion angle of the –C=N—N—C– system between two aromatic rings is −167.1 (3)°. Intramolecular O—H⋯N hydrogen bonding generates S(6) rings. In the neighbouring molecules are linked together along the c axis by weak intermolecular C—H⋯O and N—H⋯O hydrogen bonds, generating R12(6) ring motifs.

The isoniazid derivative was prepared following procedure reported by Lourenco et al., (2008). 5-methoxysalicylaldehyde (1.0 mmol) was added to isoniazid (1.0 mmol) in ethanol. After stirring for 3 h at reflux condition, the resulting mixture was concentrated at room temperature. The residue was purified by washing with cold ethanol and diethyl ether to give the pure derivative. Colourless single crystals suitable for X-ray analysis were obtained by re-crystallization from methanol.
In the absence of significant
effects, Freidel pairs were merged. The calculation of the Flack (1983) parameter was suppressed by the MERG 4 command in SHELXL97 (Sheldrick, 2008), as the lack of anomalous scatterers did not allow the determination of the from the X-ray measurements. The H atoms of the O—H and N—H groups were found from a difference Fourier map and refined freely [O1—H1 = 0.96 (4) and N2—H2 = 0.88 (4) Å]. The remaining H atoms were placed in idealized positions and allowed to ride on their parent atoms, with C—H = 0.93 and 0.96 Å for aromatic and methyl H, respectively, and Uiso(H) = 1.5Ueq(C) for methyl H and Uiso(H) = 1.2Ueq(C) for aromatic H.In the search for new biologically active compounds, isoniazid (isonicotinylhydrazine) derivatives have been found to possess potential tuberculostatic activity (Janin, 2007; Maccari et al., 2005). Here, we present the
of the title compound, (I).In the title compound (I), (Fig. 1), the dihedral angle between the pyridine (C10–C14) and benzene (C1–C6) rings is 15.17 (18)°. The C8–N1–N2–C9 torsion angle is -167.1 (3) °.
Intramolecular O1—H1···N1 hydrogen bonding generates S(6) rings (Bernstein et al., 1995) (Table 1, Fig. 2). In the
neighbouring molecules are linked together by weak intermolecular C—H···O and N—H···O hydrogen bonds (Table 1, Fig. 2), generating R12(6) ring motifs (Bernstein et al., 1995), and linking the molecules along the c axis.For the tuberculostatic activity of isoniazid (isonicotinylhydrazine) derivatives, see: Janin (2007); Maccari et al.

Geometry. Bond distances, angles etc. have been calculated using the rounded fractional coordinates. All su's are estimated from the variances of the (full) variance-covariance matrix. The cell e.s.d.'s are taken into account in the estimation of distances, angles and torsion angles |
Refinement. Refinement on F2 for ALL reflections except those flagged by the user for potential systematic errors. Weighted R-factors wR and all goodnesses of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The observed criterion of F2 > σ(F2) is used only for calculating -R-factor-obs 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. |

In the search for new biologically active compounds, isoniazid (isonicotinylhydrazine) derivatives have been found to possess potential tuberculostatic activity (Janin, 2007; Maccari et al., 2005). Here, we present the crystal structure of the title compound, (I).
In the title compound (I), (Fig. 1), the dihedral angle between the pyridine (C10–C14) and benzene (C1–C6) rings is 15.17 (18)°. The C8–N1–N2–C9 torsion angle is -167.1 (3) °.
Intramolecular O1—H1···N1 hydrogen bonding generates S(6) rings (Bernstein et al., 1995) (Table 1, Fig. 2). In the crystal structure, neighbouring molecules are linked together by weak intermolecular C—H···O and N—H···O hydrogen bonds (Table 1, Fig. 2), generating R12(6) ring motifs (Bernstein et al., 1995), and linking the molecules along the c axis.
