N′-[(E)-4-Bromo­benzyl­idene]-2-(4-isobutyl­phen­yl)propanohydrazide

Abstract

The asymmetric unit of the title compound, C20H23BrN2O, contains two independent mol­ecules (A and B), in which the orientations of the 4-isobutyl­phenyl units are different. The dihedral angle between the two benzene rings is 88.45 (8)° in mol­ecule A and 89.87 (8)° in mol­ecule B. Mol­ecules A and B are linked by a C—H(...)N hydrogen bond. In the crystal, mol­ecules are linked into chains running along the a axis by inter­molcular N—H(...)O and C—H(...)O hydrogen bonds. The crystal structure is further stabilized by C—H(...)π inter­actions. The presence of pseudosymmetry in the structure suggests the higher symmetry space group Pbca. However, attempts to refine the structure in this space group resulted in a disorder model with high R (0.097) and wR (0.257) values. The crystal studied was an inversion twin with a 0.595 (4):0.405 (4) domain ratio.

Comment

Hydrazones have been found to possess antimicrobial, anticonvulsant, analgesic, antiinflammatory, antiplatelet, antitubercular, anticancer and antitumoral activities (Bedia et al., 2006; Rollas et al., 2002; Terzioglu & Gürsoy, 2003). Aryl hydrazones are important building blocks for the synthesis of a variety of heterocyclic compounds such as pyrazolines and pyrazoles (Sridhar et al., 2003). Aryl hydrazones have been most conveniently synthesized by the reaction of aryl hydrazines with carbonyl compounds. Similarly ibuprofen is also known for their pharmaceutical activities and belongs to the class of Non-Steroidal Anti-Inflammatory Drugs (Amir & Kumar, 2007). We are interested in the synthesis and crystal structure of ibuprofen containing hydrazone derivatives (Fun et al., 2008). Prompted by these observations, it was contemplated to synthesize and report the crystal structure of the title compound.

The asymmetric unit contains two independent molecules (Fig. 1), A and B, in which the orientations of the 4-isobutylphenyl units are different (Table 1). The bond lengths (Allen et al., 1987) and angles in the molecule (Fig. 1) are within normal ranges and are comparable to a closely related structure (Fun et al., 2008). The molecule A is linked to the molecule B by C20B—H20F···N1A hydrogen bond (Fig. 1). The dihedral angle formed by the C1A-C6A and C10A-C15A benzene rings is 89.87 (8)° and that between the C1B-C6B and C10B-C15B planes is 88.45 (8)°, indicating that they are almost perpendicular to each other.

The crystal packing is consolidated by intermolecular N—H···O and C—H···O hydrogen bonds (Fig. 2) which link the independent molecules into chains parallel to the [100]. The crystal structure is further stabilized by C—H···π interactions (Table 1) involving the C1A-C6A (centroid Cg1) and C1B–C6B (centroid Cg2) benzene rings.

Experimental

The title compound was obtained by refluxing a mixture of 2-[4-(2-methylpropyl)phenyl]propanehydrazide (0.01 mol), 4-bromobenzaldehyde (0.01 mol) in ethanol (30 ml) and 3 drops of concentrated sulfuric acid for 1 h. Excess ethanol was removed from the reaction mixture under reduced pressure. The solid product obtained was filtered, washed with ethanol and dried. Single crystals suitable for X-ray analysis were obtained by slow evaporation of an ethanol-N,N-dimethylformamide (DMF) (3:1) solution.

Refinement

Atoms H1NA and H1NB were located in a difference difference Fourier map and refined freely. The remaining H atoms were positioned geometrically and refined using a riding model, with C-H = 0.93–0.98 Å and Uiso(H) = 1.2 or 1.5 Ueq(C). A rotating-group model was applied for the methyl groups. The presence of pseudo-symmetry in the structure suggests a higher symmetry space group Pbca. But attempts to refine the structure in the space group Pbca resulted in a disorder model with high R (0.097) and wR (0.257) values. Because of the presence of a pseudo-centre of symmetry, the absolute structure could not be determined. The reported Flack parameter was obtained by TWIN/BASF procedure in SHELXL (Sheldrick, 2008).

Special details

Experimental. The crystal was placed in the cold stream of an Oxford Cyrosystems Cobra open-flow nitrogen cryostat (Cosier & Glazer, 1986) operating at 100.0 (1) K.
Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds 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.
