(Received 29 November 2013; accepted 30 November 2013; online 7 December 2013)

In the title formyl nitro aryl benzoate derivative, C15H10N2O7, the benzene rings form a dihedral angle of 4.96 (3)°. The mean plane of the central ester group, C—O—C–(=O)—C (r.m.s. deviation = 0.0484 Å), is twisted away from the formyl nitro aryl and benzoate rings by 46.61 (5) and 49.93 (5)°, respectively. In the crystal, the mol­ecules are packed forming C—H⋯O inter­actions in chains which propagate along [010]. Edge-fused R33(15) rings are generated along this direction.

Comment top

The title compound, 4-formyl-2-nitrophenyl 3-nitro-2-methyl benzoate, (I), was synthesized in order to complement the structural information on the formyl nitro aryl benzoates presented in earlier jobs from our research group: 4-formyl-2-nitrophenyl 4-bromo benzoate (F4BrB) (Moreno-Fuquen et al., 2013a) and 4-formyl-2-nitrophenyl 4-cloro benzoate (F2ClB) (Moreno-Fuquen et al., 2013b). The molecular structure of (I) is shown in Fig. 1. Bond lengths and bond angles show marked similarity with their homologues F4BrB and F2ClB. The benzene rings of (I) form a dihedral angle of 4.96 (3)°, a value which is quite different from the values reported for F4BrB [62.90 (7)°] and F2ClB [19.55 (9)°] similar systems. This planar arrangement may be motivated by the intermolecular interaction between the methyl group and the nitro group of the formyl ring. The ester group C8-O2-C7(O1)-C1 is planar [r.m.s. deviation= 0.0484 Å] and is twisted away from the formyl nitro aryl and benzoate rings by 46.61 (5)° and 49.93 (5)° respectively. The nitro groups form dihedral angles with the adjacent benzene rings of 37.62 (5)° for O3-N1-O4 and 39.67 (5)° for O6-N2-O7. The crystal packing shows no classical hydrogen bonds. The molecules are packed forming weak C-H···O intermolecular interactions in one-dimensional helical chains which propagates along [010] (see Fig. 2]. The C10 atom at (x,y,z) acts as hydrogen-bond donor to formyl atom O5 at (-x-1,+y-1/2,-z+1/2+1) and C12 atom at (x,y,z) acts as hydrogen-bond donor to nitro O4 atom at (x,+y+1,+z) (see Table 1; Nardelli, 1995). The combination of these two contacts generate edge-fused rings R33(15) (Etter, 1990) along [010].

Experimental top

The reagents and solvents for the synthesis were obtained from the Aldrich Chemical Co., and were used without additional purification. The title molecule was obtained through a two-step reaction. First, 3-nitro-2-methylbenzoic acid (0.502 g, 1.575 mmol) was refluxed with thionyl chloride (5 mL) in chloroform for an hour. Then, the thionyl chloride was distilled to purify the 3-nitro-2-methyl benzoyl chloride obtained as a pale-yellow translucent liquid. The same reaction flask was rearranged and an equimolar solution of 4-hydroxy-3-nitrobenzaldehyde (0.219 g, 1.575 mmol) in acetonitrile was dropped inside it with 0.03 mL of pyridine. The reaction mixture was taken to room temperature with constant stirring for about an hour. A shiny yellow solid was obtained after leaving the solvent to evaporate. IR spectra were recorded on a FT—IR SHIMADZU IR-Affinity-1 spectrophotometer. Yellow crystals; m.p 398 (1) K.

Refinement top

All H-atoms were positioned at geometrically idealized positions with C—H distance of 0.95 Å and Uiso(H) = 1.2 times Ueq of the C-atoms to which they were bonded. The coordinates of the H14 atom were refined.

The molecular structure of (I) is shown in Fig. 1. Bond lengths and bond angles show marked similarity with their homologues F4BrB and F2ClB. The benzene rings of (I) form a dihedral angle of 4.96 (3)°, a value which is quite different from the values reported for F4BrB [62.90 (7)°] and F2ClB [19.55 (9)°] similar systems.

The C10 atom at (x,y,z) acts as hydrogen-bond donor to formyl atom O5 at (-x-1,+y-1/2,-z+1/2+1) and C12 atom at (x,y,z) acts as hydrogen-bond donor to nitro O4 atom at (x,+y+1,+z) (see Table 1; Nardelli, 1995). The combination of these two contacts generate edge-fused rings R33(15) (Etter, 1990) along [010].

Special details top

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.
