(Received 29 October 2010; accepted 2 November 2010; online 6 November 2010)

In the title compound [systematic name: 2,3-dibromo-3-(2-bromo­phen­yl)-1-(5-oxido-3-phenyl-1,2,3-oxadiazol-3-ium-4-yl)propan-1-one], C17H11Br3N2O3, the oxadiazole ring is essentially planar, with a maximum deviation of 0.003 (1) Å. The –CHBr–CHBr– chain and bromo­phenyl ring are disordered over two sets of sites with a refined occupany ratio of 0.756 (5):0.244 (5). The central oxadiazole ring makes dihedral angles of 54.07 (11) and 13.76 (18)° with the attached phenyl and the major component of the bromo-substituted benzene rings, respectively. The dihedral angle between the major and minor components of the bromo­phenyl rings is 13.4 (5)°. In the crystal structure, mol­ecules are connected by C—H⋯O hydrogen bonds, forming [010] ribbons.

Comment top

Sydnones constitute a well-defined class of mesoionic compounds that contain the 1,2,3-oxadiazole ring system. The study of sydnones still remains a field of interest because of their electronic structure and also because of the varied types of biological activities (Rai et al., 2008). Recently, sydnone derivatives were found to exhibit promising antimicrobial properties (Jyothi et al., 2008). Chalcones were obtained by the base-catalyzed condensation of 4-acetyl-3-aryl sydnones with aromatic aldehydes in alcoholic medium employing sodium hydroxide as catalyst at 0–50°C. Bromination of chalcones with bromine in glacial acetic acid afforded dibromo chalcones (Rai et al., 2007).

The molecular structure of the title compound is shown in Fig. 1. The oxadiazole (N1/N2/O1/C7/C8) ring is essentially planar, with a maximum deviation of 0.003 (1) Å for atom N1. The dibromo-substituted bromophenyl ring is disordered over two sites with a refined occupany ratio of 0.756 (5):0.244 (5). The central oxadiazole (N1/N2/O1/C7/C8) ring makes dihedral angles of 54.07 (11)° and 13.76 (18)° with the attached phenyl (C1–C6) and the bromo-substituted phenyl (C12A–C17A) rings, respectively. The dihedral angle between the major component (C12A–C17A) and the minor component (C12B–C17B) bromophenyl rings is 13.4 (5)°.

In the crystal, (Fig. 2), the molecules are connected by intermolecular C5—H5A···O3, C11A—H11B···O2 and C17A—H17A···O2 (Table 1) hydrogen bonds into ribbons along the b axis.

Experimental top

1-(31-Phenylsydnon-41-yl)-3-(o-bromophenyl)-propen-1-one (0.01 mol) was dissolved in glacial acetic acid (25–30 ml) by gentle warming. A solution of bromine in glacial acetic acid (30% w/v) was added to it with constant stirring till the yellow colour of the bromine persisted. The reaction mixture was stirred at room temperature for 1–2 hours. The solid which separated was filtered, washed with methanol and dried. It was then recrystallized from ethanol. Colourless blocks of (I) were obtained from 1:2 mixtures of DMF and ethanol by slow evaporation.

Refinement top

All H atoms were positioned geometrically [C—H = 0.93 or 0.98 Å] and were refined using a riding model, with Uiso(H) = 1.2Ueq(C). The dibromo substituted bromophenyl ring disordered over two sites with a refined occupany ratio of 0.756 (5):0.244 (5).

Special details top

Experimental. The crystal was placed in the cold stream of an Oxford Cryosystems Cobra open-flow nitrogen cryostat (Cosier & Glazer, 1986) operating at 100.0 (1) K.

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 > 2σ(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.
