The title compound, 2C16H13N3O4·C18H14N4·2CH4O, was crystallized from the reaction between 3,4,5-trihydroxybenzoylhydrazine and indole-2-carbaldehyde in a mixture of ethanol and methanol. The compound is a stoichiometric 2:1 cocrystal of the methanol-solvated reaction product, 3,4,5-trihydroxy-N′-(1H-indol-2-ylmethylidene)benzohydrazide and 1H-indole-2-carbaldehyde azine that arose unexpectedly during the synthesis. The former molecules are linked by O—H⋯O hydrogen bonds and also by π–π stacking interactions between benzoylhydrazide rings into a two-dimensional network. The methanol solvent molecules are hydrogen bonded to this network. The centrosymmetric azine molecules are not engaged in hydrogen bonding.

A solution of indole-2-carboxaldehyde (0.725 g, 5 mmol) in methanol (20 ml) was added to a solution of 3,4,5-trihydroxybenzoylhydrazine (0.92 g, 5 mmol) in ethanol (60 ml). Furthermore, 1 ml of acetic acid was added and the mixture was refluxed for 4 h. The solution was then cooled and filtered to remove the unreacted hydrazide.The filtrate was set aside at room temperature overnight and crystals of the title compound were collected.
C-bound hydrogen atoms were placed at calculated positions (C–H 0.95 Å), and were treated as riding on their parent carbon atoms, with U(H) set to 1.2Ueq(C). The nitrogen- and oxygen-bound H atoms were located in a difference Fourier map, and were refined with distance restraints of N–H 0.88±0.01 and O–H 0.84±0.01 Å.

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. |

Gallic acid (3,4,5-trihydroxybenzoic acid) derivatives have been studied for various biological activities including anticancer (Saxena et al., 2008), antioxidant and antimicrobial activity (Arunkumar et al., 2006). In order to prepare a new derivative of gallic acid, the reaction between 3,4,5-trihydroxybenzoylhydrazine and indole-2-carboxaldehyde was carried out to synthesize the related gallichydrazone; 3,4,5-trihydroxy-N'-[(1H-indol-2-yl)methylidene]benzoylhydrazide. However, a crystal suitable for X-ray diffraction was unexpectedly obtained during the synthesis.
A view of the title structure is illustrated in Fig. 1. The asymmetric unit contains two molecules of the gallic hydrazone with different conformation. In one of them, (I), the aromatic rings are nearly coplanar [dihedral angle = 11.00 (0.16) °], similar to the related previously reported structures (Khaledi et al., 2008a, 2008b, 2009a, 2009b), whereas in the other one, (II), they are highly twisted with respect to each other, the dihedral angle between the two ring planes being 52.43 (0.11) °. The crystal structure is an infinite two-dimensional, hydrogen bonded, network of gallic hydrazone molecules (Fig. 2) with methanol solvate molecules. In addition, π–π interactions between aromatic rings occur. The benzoylhydrazide rings of molecule (I) and the symmetry-related planes at (-x+2, -y, -z+1 and -x+1, -y, -z + 1) are arranged in an antiparallel manner above each other in an infinite one dimensional chain with centroid separations of 3.783 (2) Å and 3.973 (2) Å alternatively. The benzoylhydrazide ring of molecule (II) and the symmetry-related plane at (-x + 2, -y + 1, -z + 1) also interact with one another through π–π stacking, with a centroid-centroid distances of 3.703 (2) Å, leading to a dimer. The framework is interdigitated with solvate azine molecules (Fig. 4) in the ratio of one for every two hydrazone molecules. The azine constituent, which is an unexpected decomposition product of the reaction, is almost planar [maximum deviation 0.21 (1) A°] with a trans configuration about N—N single bond, similar to its indole-3-carbaldehyde analogue (Rizal et al., 2008).
