Abstract top

The title compound, C13H9N3O3, crystallizes with two identical but differently oriented molecules in the asymmetric unit, the dihedral angle between the fused-ring systems of the two molecules being 64.39 (7)°. The two prop-2-ynyl chains are located on opposite sides of the molecule and are nearly perpendicular to the fused ring plane, as indicated by the C-N-C-C torsion angles in the range 106.0 (3)-113.4 (3)°. In the crystal, the two molecules are linked through C-H...O hydrogen bonds into dimers, which are subsequently linked by further C-H...O interactions, building a three-dimensional network.

Comment top

Benzimidazoles are very useful intermediates/subunits for the development of molecules of pharmaceutical or biological interest. Benzimidazole and its derivatives are an important class of bioactive molecules in the field of drugs and pharmaceuticals. Benzimidazole derivatives have found applications in diverse therapeutic areas including anti-ulcers, anti-hypertensive, anti-viral, anti-fungal, anti-cancers, (Horton et al., 2003; Kim et al., 1996; Roth et al., 1997).

As a continuation of our research work devoted to the development of substituted benzimidazol-2-one derivatives (Ouzidan et al., 2011a, 2011b), we report in this paper the synthesis of new benzimidazol-2-one derivative by action of propargyl bromide with 1H-benzo[d]imidazol-2(3H)-one in the presence of a catalytic quantity of tetra-n-butylammonium bromide under mild conditions to furnish two compounds: mono-substituted (Ouzidan et al., 2011c) and di-substituted (Scheme 1).

The asymmetric unit of title compound, 1,3-Bis(prop-2-ynyl)-5-nitro-1H-benzo [d]imidazol-2(3H)-one, contains two molecules. Each of them is build up from two fused five- and six-membered rings liked to nitro group and to two prop-2-ynyl chains in opposite sides as shown in Fig. 1. The fused ring systems are almost planar, with the largest deviations from the mean planes being -0.005 (2) A° and 0.007 (3) A° for the C1 and C14 atom, respectively. In each molecule, the two prop-2-ynyl chains are nearly perpendicular to the fused ring plan as indicated by the torsion angles: C1–N1–C8–C9 = 111.8 (3)°; C1–N2–C11–C12 = 106.0 (3)°; C14–N4–C21–C22 = 113.4 (3)° and C14–N5–C24–C25 = 109.8 (3)°. The fused ring system belonging to the first molecule makes dihedral angle of 64.39 (7) ° with that of the second molecule. The difference between the two independent molecules lies in the crystallographic environment of each in addition to their orientations in the crystal. Indeed, in molecule I (C1 to C13), carbon C5 is involved in a C5—H5···O6 intermolecular hydrogen bond while in molecule II (C14 to C26) the corresponding carbon (C18 ) is not engaged in such a bond. In the crystal, the two molecules are linked through C8–H8A···O4 and C21–H21B···O1 hydrogen bonds in order to form dimers, which are linked together by the other C–H···O hydrogen bonds to build a three-dimensional network as shown in Fig.2 and Table 2.

Experimental top

To 5-nitro-1H-benzo[d]imidazol-2(3H)-one (0.2 g, 1.1 mmol), potassium carbonate (0.30 g, 2.2 mmol) and tetra-n-butylammonium bromide (0.07 g, 0.2 mmol) in DMF (15 ml) was added propargyl bromide (2.2 mmol). Stirring was continued at room temperature for 6 h. The salt was removed by filtration and the filtrate concentrated under reduced pressure. The residue was separated by chromatography on a column of silica gel with hexane/ethyl acetate (2/1) as eluent. Colourless crystals were isolated when the solvent was allowed to evaporate. Yield: 82%,mp: 415–417 K.

Refinement top

All H atoms could be located in a difference Fourier map. However, they were placed in calculated positions with C—H = 0.93 Å (aromatic), N—H = 0.86 and C—H = 0.97 Å (methylene) and refined as riding on their parent atoms with Uiso(H) = 1.2 Ueq (C, N).

In the absence of significant anomalous scattering, the absolute configuration could not be reliably determined and thus 2580 Friedel pairs were merged.

Special details top

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.
