The title compounds, C19H16ClNO5, (I), and C19H15Cl2NO5, (II), both crystallize in the monoclinic P21/n. They differ essentially in the orientation of the methyl acetate group, with the C=O bond directed towards the NO2 group in (I) but away from it in (II). In compound (I), the mean plane of the methyl acrylate unit is planar, with a maximum deviation of 0.0044 (2) Å for the methyl C atom, while in (II) this deviation is 0.0147 Å. The interplanar angles between the two aromatic rings are 74.87 (9) and 75.65 (2)° for compounds (I) and (II), respectively. In both compounds, the methyl acrylate and nitrovinyl groups each adopt an E conformation about the C=C bond. In the crystal of (I), molecules are linked by C—H⋯O hydrogen bonds forming chains along the b axis. The chains are linked via C—H⋯Cl hydrogen bonds, forming sheets parallel to the ab plane. The sheets are linked via C—H⋯π interactions, forming a three-dimensional structure. In the crystal of (II), molecules are linked by pairs of C—H⋯O hydrogen bonds, forming inversion dimers with an R22(30) ring motif. The dimers are linked via C—H⋯O hydrogen bonds, forming sheets parallel to the ac plane and enclosing R44(28) ring motifs. The sheets are linked via parallel slipped π–π interactions (intercentroid distances are both ca 3.86 Å), forming a three-dimensional structure.
1. Chemical context
Recently, 2-cyanoacrylates have been used extensively as agrochemicals because of their unique mechanism of action and good environmental profiles (Govindan et al., 2011). Phenyl acrylates and their derivatives are important compounds because of their agrochemical and medical applications (De Fraine & Martin, 1991). Cinnamic acid derivatives have received attention in medicinal research as traditional as well as recently synthetic antitumor agents (De et al., 2011). They also possess significant antibacterial activity against Staphylococcus aureus (Xiao et al., 2008). In addition, different substitutions on the basic moiety lead to various pharmacological activities, such as anti-oxidant, hepatoprotective, anxiolytic, insect repellent, antidiabetic and anticholesterolemic (Sharma, 2011). Against this background, the title compounds were synthesized and we report herein on their crystal structures.
2. Structural commentary
The title compounds, (I) and (II), crystallized in the monoclinic P21/n with Z = 4; their molecular structures are illustrated in Figs. 1 and 2, respectively. In compound (I), the methyl acrylate unit is essentially planar, with a maximum deviation of 0.0044 (2) Å for atom C12, and forms dihedral angles of 84.04 (9) and 50.23 (9)° with the benzene rings (C3–C8) and (C14–C19), respectively. Likewise, in compound (II), the methyl acrylate unit is essentially planar, with a maximum deviation of 0.0147 (2) Å for atom C12, and forms dihedral angle of 73.20 (9) and 42.81 (9)° with benzene rings (C3–C8) and (C14–C19), respectively. In compound (I), the rings (C3–C8) and (C14–C19) are almost normal to one another, making a dihedral angle of 74.87 (9)°. In the case of compound (II), the corresponding dihedral angle is 75.65 (2)°. The title molecules exhibit structural similarities with the related structure, (Z)-methyl 3-(2,4-dichlorophenyl)-2-[(2-formylphenoxy)methyl]acrylate (Gangadharan et al., 2011).
The methyl acrylate moieties adopt an extended conformation, as is evident from the torsion angles O4—C11—C10—C13 = 170.6 (2)°, O5—C11—C10—C13 = −8.5 (2)°, C9—C10—C11—O4 = −5.5 (2)° and C9—C10—C11—O5 = 175.5 (1)° for compound (I), while the corresponding angles in compound (II) are −2.9 (5), 177.7 (3), 173.0 (3) and −6.3 (4)°, respectively. The extended conformation is supported by the fact that the bond angles involving the carbonyl O atoms are invariably enlarged (Schweizer & Dunitz, 1982).
The significant difference in the bond lengths O5—C11 and O5—C12, which are 1.324 (2) and 1.444 (2) Å, respectively, for compound (I), and 1.328 (4) and 1.440 (4) Å, respectively, for compound (II), can be attributed to a partial contribution from the O−—C=O+—C resonance structures of the O5—C11(=O4)—C10 group (Merlino et al., 1971). This feature, commonly observed for the carboxylic ester group of substituents in various compounds gives average values of 1.340 and 1.447 Å, respectively (Varghese et al., 1986).
In both compounds, the nitrovinyl groups [C2=C1—N1(O1,O2)], have an E conformation about the C2=C1 bond. In (I), its mean plane makes a dihedral angle of 2.025 (9)° with the benzene ring (C3–C8) to which it is attached, while in compound (II), the corresponding dihedral angle is much larger, at 14.78 (16) °.
3. Supramolecular features
In the crystal of (I), adjacent molecules are linked by C—H⋯O hydrogen bonds forming chains along the b-axis direction (Table 1 and Fig. 3). The chains are linked via C—H⋯Cl hydrogen bonds, forming sheets parallel to the ab plane (Fig. 4 and Table 1). The sheets are linked via C—H⋯π interactions, forming a three-dimensional structure (Table 1).
In compound (II), molecules are linked by pairs of C—H⋯O hydrogen bonds, forming inversion dimers enclosing an R22(30) ring motif (Table 2 and Fig. 5). The dimers are linked by further C—H⋯O hydrogen bonds, forming sheets parallel to the ac plane and enclosing R44(28) ring motifs (Table 2 and Fig. 5). The sheets are linked via slipped parallel π–π interactions, forming a three-dimensional structure, Fig. 6 [Cg1⋯Cg1i = 3.863 (2) Å, inter-planar distance = 3.487 (1) Å, slippage 1.662 Å; Cg1 is the centroid of ring C3–C8; symmetry code: (i) −x + 1, −y, z + 1, and Cg2⋯Cg2ii = 3.861 (2) Å, inter-planar distance = 3.506 (2) Å, slippage = 1.617 Å; Cg2 is the centroid of ring C14–C19; symmetry code: (ii) −x + 1, −y, −z + 2].
4. Database survey
A search of the Cambridge Structural Database (CSD, Version 5.37, November 2015; Groom & Allen, 2014) for the methyl (E)-2-(phenoxymethyl)-3-phenylacrylate gave 12 hits. There is a great variety in the dihedral angle involving the two aromatic rings; from a minimum of ca 47.2° in (E)-methyl 2-({2-ethoxy-6-[(E)-(hydroxyimino)methyl]phenoxy}methyl)-3-phenylacrylate (CSD code: ZARDAT; Govindan et al., 2012) to a maximum of ca 88.4° in methyl (E)-2-[(2-nitrophenoxy)methyl]-3-phenylacrylate (CSD code: PAWFIE; Anuradha et al., 2012). In the title compounds, this dihedral angle is 74.87 (9)° in (I) and 75.65 (2)° in (II).
5. Synthesis and crystallization
The title compounds were prepared in a similar manner using a mixture of methyl (E)-3-(2-chlorophenyl)-2-{[2-(2,2-dicyanovinyl)phenoxy]methyl}acrylate (1 mmol) for compound (I), and methyl (E)-2-{[4-chloro-2-(2,2-dicyanovinyl)phenoxy]methyl}-3-(2-chlorophenyl)acrylate (1 mol) for compound (II), dissolved in nitromethane (5 mol) in toluene (3 ml) with a catalytic amount of cinchona alkaloid (0.005 mmol %). The resulting solutions were stirred for 4 h at room temperature. The consumption of the starting materials was monitored by TLC. After completion of the reaction, DMAP (0.020 mol %) and di-tert-butyl dicarbonate (1.2 equiv) were added and the solutions of the corresponding crude products were stirred at 318–323 K for 2 h, followed by TLC (20% EtOAc and petroleum ether). The solvents were removed under reduced pressure and the residues purified by on silica gel (3:97%, ethylacetate and petroleum ether) to afford pure products. The purified compounds were recrystallized from ethanol, by slow evaporation of the solvent, yielding block-like crystals of compounds (I) and (II), suitable for X ray diffraction analysis.

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. |

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. |
