1-[(Bromomethyl)(phenyl)methylene]-2-(2,4-dinitrophenyl)hydrazine

A. Salhin, N. Abdul Razak and I. A. Rahman

Abstract top

The title compound, C14H11BrN4O4, comprises two crystallographically independent molecules (A and B) in the asymmetric unit. In molecule B, intramolecular bifurcated N-H...O and N-H...Br hydrogen bonds and in molecule A, an intramolecular N-H...O hydrogen bond generate S(6) ring motifs. The dihedral angle between the phenyl and benzene rings is 5.44 (6) in molecule A and 7.63 (6)° in molecule B. The ortho- and meta-nitro substituents make dihedral angles of 6.67 (15) and 2.26 (15)° to the attached benzene ring in molecule A and 6.37 (17) and 5.81 (16)° in molecule B. The Br atom in molecule B is disordered over two positions with a refined site-occupancy ratio of 0.61 (3):0.39 (3). Interesting features of the crystal structure are the short Br...N [3.257 (3)-3.294 (4) Å], Br...O [3.279 (3)-3.307 (4) Å] and O...O [2.9319 (16)-2.9995 (16) Å] contacts, which are shorter than the sum of the van der Waals radii of these atoms. The crystal structure is further stabilized by intermolecular C-H...O and [pi]-[pi] interactions [centroid-centroid distances = 3.6643 (8)-3.8514 (8) Å].

Comment top

In view of the importance of hydrazone derivatives in chemical and biological applications (Rollas & Küçükgüzel, 2007; Shao et al., 2008), a series of hydrazone derivatives has been prepared in our laboratory, from which several X-ray structures have been reported (Salhin et al., 2007; Tameem et al., 2006, 2007 and 2008).

The title compound, C14H11BrN4O4, comprises two crystallographically independent molecules (A, B) in the asymmetric unit. In molecule B, intramolecular bifurcated N—H···O and N—H···Br hydrogen bonds and in molecule A, an intramolecular N—H···O hydrogen bond generate S(6) ring motifs. The dihedral angle between the phenyl rings in molecules A and B are 5.44 (6) and 7.63 (6)°, respectively. The ortho and meta nitro-substituents make the dihedral angles of 6.67 (15) and 2.26 (15)° in molecule A and 6.37917) and 5.81 (16)° to the benzene ring they are attached. The bromine group was disordered over two positins with a refined site-occupancy ratio of 0.61 (3)/0.39 (3) in molecule B. The crystal structure is further stabilized by intermolecular C—H···O and π-π [Cg1··· Cg1iii = 3.6643 (8) Å, (iii) 2 - x, -y, 1 - z; Cg1··· Cg4iv = 3.7308 (8) Å, (iv) 1 - x, -y, 1 - z; Cg1···Cg2iv = 3.7013 (8) Å; Cg2···Cg3iv = 3.7012 (8) Å; Cg3···Cg4v = 3.8514 (8) Å, (v) -x, -y, 2 - z: Cg1, Cg2, Cg3, Cg4 are the centroids of the C1A–C6A, C8A–C13A, C1B–C6B, and C8B–C13b rings].

The interesting features of the crystal structure are short Br1A···N4Avi [3.257 (3), (vi) 3/2-x,1/2+y,1/2-z], Br1C···N4Avi [3.294 (4) Å], Br1A···O3Aviii [3.279 (3), (viii) 3/2-x,-1/2+y,1/2-z], Br1C···O3Avii [3.307 (4) Å], O2A···O3Aiv [2.9319 (16) Å], and O1A···O4Bvii [2.9995(160 Å, (vii) 1/2-x,1/2+y,3/2-z] contacts which are shorter than the sum of the van der Waals radii of these atoms.

Experimental top

2,4-Dinitrophenylhydrazine (0.5 g, 2.5 mmol) was dissolved in ethanol (10 ml), and H2SO4 solution (98%, 1 ml) was added slowly with stirring. The solution was heated on a water bath for several minutes until it cleared. An ethanol solution (5 ml) of α-bromoacetophenone (0.5 g, 2.5 mmol) was dropped slowly into the above solution with continuous stirring. The mixture was heated for another 5 minutes on water bath. On cooling to room temperature, an orange precipitate was formed. Recrystallization from ethanol solution produced the crystals of the title compound.

Refinement top

The N-bound hydrogen atoms were located from the difference Fourier map and refined freely, see Table 1. The rest of the H atoms were positioned geometrically and refined as riding model with C—H = 0.93–0.97 and Uiso(H) = 1.2 Ueq(C).

Special details top

Experimental. The low-temperature data was collected with the Oxford Cyrosystem Cobra low-temperature attachment.

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.
