6-(4-Bromo­phen­yl)-2-eth­oxy-4-(2,4,5-trimethoxy­phen­yl)nicotinonitrile1

Abstract

There are two mol­ecules in the asymmetric unit of the title compound, C23H21BrN2O4, which differ in the conformation of their ethoxy residues, i.e. almost co-planar with the pyridine ring in one mol­ecule [C—O—C—C = −174.0 (2)°] but almost perpendicular in the other [C—O—C—C = 92.8 (3)°]. The dihedral angles between the central pyridine ring and the 4-bromo­phenyl and 2,4,5-trimethoxy­phenyl rings are 11.05 (12) and 63.78 (12)°, respectively, in one mol­ecule; the corres­ponding angles in the other mol­ecule are 30.38 (13) and 65.38 (13)°, respectively. In the crystal structure, pairs of mol­ecules are arranged in a face-to-face sandwich structure which further stacks along the b axis. The crystal packing features C—H(...)π inter­actions and Br(...)O [3.5417 (17) Å], Br(...)C [3.748 (3) Å], C(...)N [3.376 (4) Å] and C(...)O [3.351 (3)–3.409 (3) Å] contacts. Finally, π(...)π inter­actions [centroid(...)centroid distances = 3.6346 (19) and 3.6882 (19) Å] are observed.

Comment

Substituted pyridine derivatives have been claimed to have several biological activities (Borgna et al., 1993; Goda et al., 2004). We have previously reported the syntheses and crystal structures of the nicotinonitrile derivatives (Chantrapromma et al., 2009; 2010). In continuation of our research into the synthesis of antimicrobial agents, the title malononitrile derivative was synthesised and studied for its anti-bacterial activities. However, our results showed that the title compound does not possess anti-bacterial activities. Herein, we report the crystal structure of the title compound (I).

There are two crystallographic independent molecules A and B in the asymmetric unit of (I) (Fig. 1) with differences in conformation of the ethoxy group distinguishing them. In molecule A the ethoxy residue is almost co-planar with the pyridine ring [C11A–O1A–C18A–C19A = -174.0 (2) °] whereas it is almost perpendicular in molecule B [C11B–O1B–C18B–C19B = 92.8 (3) °]. The dihedral angles between the central pyridine ring and the 4-bromophenyl and 2,4,5-trimethoxyphenyl rings are 11.05 (12) and 63.78 (12) ° respectively in molecule A whereas the corresponding pair of angles in molecule B are 30.38 (13) and 65.38 (13) °. All three methoxy groups are nearly co-planar with the attached benzene ring [torsion angles C20–O2–C13–C14 = -11.6 (4) °, C21–O3–C15–C16 = 180.0 (2) ° and C22–O4–C16–C17 = 8.1 (4) ° in molecule A; and the corresponding values are -5.5 (4), -175.5 (2) and -7.7 (4) ° in molecule B]. Weak intramolecular C1A—H1AA···N1A (in molecule A) and C18B–H18C—N1B (in molecule B) interactions generate S(5) ring motifs (Bernstein et al., 1995). The bond distances are comparable with those in closely related structures (Chantrapromma et al., 2009; 2010).

In the crystal structure (Fig. 2), the molecules are arranged into a face-to-face sandwich-like structure which further stack along the b axis. The crystal is consolidated by C—H···π interactions (Table 1) and Br···O [3.5417 (17) Å], Br···C [3.748 (3) Å], C···N [3.376 (4) Å] and C···O [3.351 (3) - 3.409 (3) Å] contacts. Finally, π···π interactions with the distances of Cg1···Cg4 = 3.6346 (15) Å (symmetry code: 1-x, 1-y, 1-z) and Cg2···Cg3 = 3.6882 (15) Å (symmetry code: -x, 1-y, 1-z) are observed; Cg1, Cg2, Cg3 and Cg4 are the centroids of C7A–C11A/N1A, C12A–C17A, C7B–C11B/N1B, and C12B–C17B rings, respectively.

Experimental

(E)-1-(4-Bromophenyl)-3-(2,4,5-trimethoxyphenyl)prop-2-en-1-one (0.57 g, 0.0015 mol) was added with continuous stirring to a freshly prepared sodium alkoxide solution (0.0014 mol of sodium in 100 ml of ethanol). Malononitrile (1.3 g, 0.02 mol) was then added with continuous stirring at room temperature until the precipitate separated out. The resulting solid was filtered (yield 68 %). Colorless needle-shaped single crystals of the title compound were obtained by recrystallization from ethanol by the slow evaporation of the solvent at room temperature after several days, Mp. 460-461 K.

Refinement

All H atoms were positioned geometrically and allowed to ride on their parent atoms, with d(C—H) = 0.93 Å for aromatic-H, 0.97 for CH2 and 0.96 Å for methyl-H 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.

Special details

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 > 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.
