(Received 25 January 2011; accepted 7 March 2011; online 12 March 2011)

In the crystal structure of the title compound, C15H13BrN2O5·CH3OH, the methanol solvent mol­ecule links symmetry-related mol­ecules through O—H⋯O and N—H⋯O hydrogen bonds. Further inter­molecular O—H⋯O hydrogen bonds link symmetry-related mol­ecules, leading to the formation of a three-dimensional network. Two of the H atoms involved in hydrogen bonding are disordered. The dihedral angle between the rings is 5.64 (14)°.

Comment top

Schiff base compounds have received much attention in recent years. Some of the complexes have been found to have antibacterial and antitumor properties (Brückner, et al.,2000; Harrop et al.,2003; Ren et al.,2002). As part of our research programme on Schiff base compounds (Diao, 2007; Diao et al., 2007; Li et al., 2007; Huang et al., 2007), we report here the structure of the title compound.

The title compound co-crystallizes with one methanol molecule (Fig. 1), which links symmetry-related molecules through O—H···O and one N—H···O hydrogen bonds. In the crystal structure, further intermolecular O—H···O hydrogen bonds link symmetry-related molecules (Table 1), forming a three-dimensional network (Fig.2). The H atoms bonded to O2 and O5 are disordered over two positions. All positions take part in intermolecular hydrogen bonds.

Experimental top

2-Bromo-5-hydroxy-4-methoxybenzaldehyde (0.1 mmol, 23.1 mg) and 3,5-Dihydroxybenzhydrazide (0.1 mmol, 16.8 mg) were dissolved in a methanol solution (10 ml). The mixture was stirred at room temperature for 1 h and filtered. After keeping the filtrate in air for three days, colorless block-like crystals were formed.

Refinement top

The H2 atom bonded to N2 was located in a difference map and refined freely, other H atoms were placed in geometrically idealized positions and allowed to ride on their parent atoms, O—H=0.82,C—H=0.93 for phenyl, 0.96 for methyl H atoms, with Uiso(H)=1.2Ueq(C) for phenyl and 1.5eqU(C) for methyl and hydroxyl groups. H atoms bonded to O2 and O5 were split over two positions with a fixed occupation factor of 0.5.

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.
