(Received 19 September 2011; accepted 24 September 2011; online 30 September 2011)

There are three independent mol­eculesi n the asymmetric unit of the title compound, C18H16BrN3O3, in which the dihedral angles between the indole and benzene rings are 76.9 (2), 4.9 (2), and 70.9 (2)°. All three mol­ecules exist in a trans configuration with respect to the methyl­idene units. In each mol­ecule, there is one intra­molecular O—H⋯N hydrogen bond. In the crystal, N—H⋯O hydrogen bonds occur.

Comment top

In the last few years, hydrazones have attracted much attention for their syntheses and crystal structures (Hashemian et al., 2011; Lei, 2011; Shalash et al., 2010). As a continuation of our work on such compounds (Li, 2011a,b), the author reports herein on the crystal structure of the new title hydrazone compound.

In the asymmetric unit of the title compound there are three (A, B and C) independent molecules (Fig. 1). The bond distances and angles are comparable to those observed in similar compounds (Li, 2011a,b). The dihedral angles between the indole ring and the benzene ring in the three molecules are 76.9 (2), 175.1 (2), and 70.9 (2)° for molecules A, B and C, respectively. All the molecules exist in the trans configuration with respect to the methylidene units. In each molecule there is an O—H···N intramolecular hydrogen bond (Table 1).

Experimental top

A mixture of 1H-indole-3-carbohydrazide (0.189 g, 1 mmol) and 5-bromo-2-hydroxy-3-methoxybenzaldehyde (0.231 g, 1 mmol) in 30 ml of ethanol containing few drops of acetic acid was refluxed for about 1 h. On cooling to room temperature, a solid precipitate was formed. The solid was filtered and then recrystallized from methanol. Colourless crystals, suitable for X-ray diffraction analysis, were obtained by slow evaporation of a solution of the title compound in methanol.

Refinement top

The NH H-atoms were located from a difference Fourier map and were freely refined. The OH and C-bound H-atoms were positioned geometrically and refined using a riding model: O—H = 0.82 Å, C—H = 0.93 – 0.97 Å, for CH, CH2 and CH3 H-atoms, with Uiso(H) = k × Ueq(O,C), where k = 1.5 for OH and CH3 H-atoms, and k = 1.2 for all other H-atoms.

Special details top

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.
