In the title compound, C12H11N3O3·2H2O, the dihedral angle formed by the planes of the pyridine and the furan rings of the organic carbohydrazide molecule is 4.66 (7)°. In the crystal, these molecules form stacks along the b-axis direction, neighbouring molecules within each stack being related by inversion and the shortest distance between the centroids of the pyridine and furan rings being 3.714 (1) Å. Molecules from neighboring stacks are linked by pairs of N—H⋯O hydrogen bonds. The water molecules fill the channels between the stacks being linked by O—H⋯O hydrogen bonds into helices along [010]. Besides this, water molecules are involved in O—H⋯N and O—H⋯O hydrogen bonds with the carbohydrazide molecules, thus forming a three-dimensional network, augmented by weak C—H⋯O interactions.

The title compound was prepared by adapting a reported procedure (Sreeja & Kurup, 2005). To a warm methanolic solution of 5-(hydroxymethyl)furan-2-carbaldehyde (0.126 g, 1 mmol), a methanolic solution of pyridine-4-carbohydrazide (0.137 g, 1 mmol) was added and the resulting solution was stirred well with slight heating for 75 minutes. A colorless compound formed was filtered off, washed with water, ethanol and finally with ether and dried. Single crystals suitable for X-ray diffraction studies were obtained by recrystallization from a mixture of methanol, ethanol and DMF.
All H atoms on C were placed in calculated positions, guided by difference maps, with C–H bond distances 0.93–0.97 Å. H atoms were assigned as Uiso(H)=1.2Ueq(carrier) or 1.5Ueq (methyl C). The H atoms of the water molecule were located from difference maps and restrained using DFIX and DANG instructions. Omitted owing to disagreement was the reflection (1 1 0).

Geometry. All s.u.'s (except the s.u. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell s.u.'s are taken into account individually in the estimation of s.u.'s in distances, angles and torsion angles; correlations between s.u.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell s.u.'s is used for estimating s.u.'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. |

Heterocyclic carbohydrazides are compounds with a wide spectrum of biological and analytical applications. They form stable metal chelates which find applications in molecular sensing (Bakir & Brown, 2002). The title compound is a derivative of isoniazid which is one of the first line drug used in the treatment of tuberculosis. A number of hydrazones derived from isoniazid were reported to be active antitubercular agents and were found to be less toxic than isoniazid (Rollas & Kucukguzel, 2007).
The compound crystallizes in monoclinic P21/c space group. The molecule exists in a E configuration with respect to the C7=N3 bond, typical of such kind of compounds (Reshma et al., 2012), with the C8—C7—N3—N2 torsion angle of 178.04 (11)° (Fig 1). The N3—N2—C6—O1 torsion angle of -2.72 (18)° indicates the cis configuration of the O1 atom with respect to the hydrazine nitrogen atom N3 (Nair et al., 2012). C7═N3 [1.267 (3) Å] and C6═O1 [1.217 (8) Å] bond distances are very close to the formal double C═N and C═O bond lengths (Prasanna, et al., 2013) confirming that the carbohydrazide exists in solid state as an amido tautomer.
Seven classical hydrogen bonds are present in the crystal (Fig. 2). One of the nitrogen atoms of pyridine-4-carbohydrazide molecule is involved in classical intermolecular hydrogen bond of the N—H···O type with oxygen atom of the hydroxymethyl group of the neighboring molecule with a D···A distance of 2.8483 (16) Å. There are two hydrogen bonds of the O—H···O type between the two water molecules: O2S—H2B···O1S and O1S—H1B···O2S with D···A distances of 2.9146 (18) Å and 2.7923 (17) Å, respectively. Each water molecule is involved in other O—H···O and O—H···N hydrogen bonds: O2S—H2A···O1 and O3—H3'···O1S with D···A distances of 2.9647 (15) Å and 2.7937 (16) Å and O2S—H2A···N3 and O1S—H1A···N1 with D···A distances of 3.2272 (17) Å and 2.8501 (16) Å, respectively. Additionally, there are non-classical intermolecular C—H···O hydrogen bonds between the hydrogen atoms attached to C4 and C12 carbon atoms and the O3 and O1 atoms of the neighboring molecule with D···A distances of 3.390 (2) Å and 3.362 (2) Å, respectively. These interactions are augmented by weak π···π interactions which connect the molecules with a centroid-centroid distances of 3.714 (1) Å and 3.760 (1) Å (Fig. 3). The packing diagram showing the molecular assembly of the title compound along the b axis is shown in Fig. 4.
