In the title compound, C14H11BrN2O4, the amide segment makes dihedral angles of 23.4 (2) and 20.5 (2)° with the benzene rings, while the dihedral angle between the bezene rings is 2.90 (8)°. The nitro and meth­oxy groups are almost coplanar with their bound benzene ring, with the r.m.s. deviation for the 11 non-H atoms being 0.0265 (1) Å. An intra­molecular N—H⋯O hydrogen bond generates an S(6) ring motif. In the crystal, mol­ecules are linked into [2-10] chains by weak C—H⋯O and C—H⋯Br inter­actions, which form an R22(8) motif between pairs of mol­ecules in the chain. A Br⋯O [3.2018 (12) Å] short contact also occurs.

Comment top

As part of our research in medicinal chemistry, the title benzamide derivative (I) was synthesized with a hope that it may exhibit anticancer and/or anti-alzheimer activities. Herein, its crystal structure was reported.

The molecule of the title benzamide derivative (Fig. 1), C14H11BrN2O4, is not planar as the plane of the middle N-C=O segment makes the dihedral angles of 23.4 (2) and 20.5 (2) ° with the C1–C6 and C8–C13 benzene rings, respectively whereas the dihedral angle between the two benzene rings is 2.90 (8)°. In the 4-methoxy-2-nitrophenyl moiety, the nitro and methoxy groups are co-planar with the bound benzene ring with the r.m.s. deviation of 0.0265 (1) Å for the eleven non-H atoms [C8–C14/N2/O2–O4] and the torsion angles O2–N2–C9–C8 = -3.8 (2)°, O3–N2–C9–C8 = 175.88 (15)° and C14–O4–C11–C12 = 3.5 (2)°. An intramolecular N1—H1N1···O2 hydrogen bond generates a S(6) ring motif (Bernstein et al., 1995). Bond distances are comparable with those in related structures (Johnston & Taylor, 2011; Li & Cui, 2011 and Saeed et al., 2008).

In the crystal (Fig. 2), the molecules are linked into [210] chains by weak C—H···O and C—H···Br interactions forming R22(8) motifs. Br1···O2iii[3.2018 (12) Å; (iii) = -x, 2-y, -z] short contact is presented.

Experimental top

A mixture of 4-bromobenzoyl chloride (0.20 g, 0.91 mmol) and 4-metoxy-2-nitroaniline (0.23 g, 1.40 mmol) in anhydrous acetone (20 ml) was refluxed for 4 h. An orange solid was formed, which was filtered and washed with water. Orange blocks of the title compound were recrystallized from ethylacetate by slow evaporation of the solvent at room temperature after a week, Mp. 434-436 K.

Refinement top

Amide H atom was located in a difference map and refined isotropically. The remaining H atoms were positioned geometrically and allowed to ride on their parent atoms, with d(C-H) = 0.95 Å for aromatic and CH and 0.98 Å for CH3 atoms. The Uiso values were constrained to be 1.5Ueq of the carrier atom for methyl H atoms and 1.2Ueq for the remaining H atoms. A rotating group model was used for the methyl groups. The highest residual electron density peak is located at 0.75 Å from Br1 and the deepest hole is located at 0.85 Å from Br1.

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 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 > 2sigma(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.
