The title compound was synthesized according to the literature method (Deng et al., 2005): acetone (25 mmol) and isonicotinyl hydrazine (22 mmol) were dissolved in anhydrous ethanol (40 ml) and refluxed for 5 h, and a yellow precipitate was obtained, which was recrystalized from ethanol and diethyl ether (1:1 v/v) to yield yellow blocks of (I) after two days in an ice box.
The N-bonded H atom was located in a difference map and freely refined. The C-bonded H atoms were placed in calculated positions with C—H = 0.93–0.96 Å and refined as riding with Uiso(H) = 1.2Ueq(C) or 1.5Ueq(methyl C).

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. |

Isoniazid (isonicotinic acid hydrazide, INH) continues to be the most widely used chemotherapeutic agent for the treatment of tuberculosis (Fox & Mitchison, 1975). Some INH hydrazide–hydrazones were reported to have lower toxicity than hydrazides because of the blockage of the –NH2 group (Kucukguzel et al.2003). In this paper, we report the structure of the title compound, (I), (Fig. 1).
The bond lengths and angles for (I) are within their normal ranges (Allen et al., 1987). The dihedral angle between the mean planes on the N1/C1–C5 ring and the O1/N2/N3/C6 grouping is 48.97 (12)°.
As shown in Fig. 2, the crystal structure is stabilized by bifurcated intermolecular N—H···(N,O) hydrogen bonds (Table 1) and C—H···O interactions leading to chains of molecules.
