In the racemic title compound, C24H25NO9, the dihedral angle between the planes of the two benzene-ring systems is 80.16 (6)°, while the side-chain conformation is stabilized by a methyl­ene–carboxyl C—H⋯O hydrogen bond. Weak inter­molecular C—H⋯O hydrogen bonds form inversion dimers [graph set R22(16)] which are linked into chains extending along a. Further C—H⋯O hydrogen bonding extends the structure along b through cyclic R22(10) motifs. Although no ππ aromatic ring inter­actions are present in the structure, C—H⋯π ring inter­actions across c generate an overall three-dimensional supra­molecular structure.

1. Chemical context

The formation of C—C bonds by the Michael addition of the appropriate carboanionic reagents to α,β-unsaturated car­bonyl compounds is one of the most useful methods of remote functionalization in organic synthesis (Mather et al., 2006[Mather, B. D., Viswanathan, K., Miller, K. M. & Long, T. E. (2006). Prog. Polym. Sci. 31, 487-531.]; Little et al., 1995[Little, R. D., Masjedizadeh, M. R., Wallquist, O. & McLoughlin, J. I. (1995). Org. React. 47, 315-552.]). In particular, a much studied reaction is the conjugate addition of malonates to chalcones. Compounds with the chalcone backbone were reported to possess a wide range of biological activities, such as nematicidal, anti­fungal, anti­allergenic, anti­microbial, anti­cancer, anti­malarial and anti­feedant properties. Malonates are traditionally regarded as important materials for synthesizing the key inter­mediates of numerous active substances, but are rarely found as pharmacophores belonging to the target compounds (Lopez et al., 2001[Lopez, S. N., Castelli, M. V., Zacchino, S. A., Dominguez, J. N., Lobo, G., Charris-Charris, J., Cortes, J. C. G., Ribas, J. C., Devia, C., Rodriguez, A. M. & Enriz, R. D. (2001). Bioorg. Med. Chem. 9, 1999-2013.]; Chen et al., 2016[Chen, Z., Li, P., Hu, D., Dong, L., Pan, J., Luo, L., Zhang, W., Xue, W., Jin, L. & Song, B. (2016). Arab. J. Chem. In the press. doi: 10.1016/j. arabjc. 2015.05.003.]). Therefore, a catalytic version of the Michael addition of dialkyl malonates to chalcones in the presence of different catalysts has been studied extensively in recent years. Many phase-transfer-catalyzed methods that are simple and environmentally friendly have been developed for the Michael reaction (Shioiri, 1997[Shioiri, T. (1997). In Handbook of Phase-Transfer Catalysis, edited by Y. Sasson & R. Neumann. London: Blackie Academic and Professional.]). This new racemic compound was prepared in a phase-transfer reaction using a sugar-based crown ether as the catalyst (Rapi et al., 2016[Rapi, Z., Bakó, P., Grün, A., Nemcsók, T., Hessz, D., Kállay, M., Kubinyi, M. & Keglevich, G. (2016). Tetrahedron Asymmetry. In the press.]).

2. Structural commentary

The mol­ecular structure of the racemic title compound is shown in Fig. 1[link]. In this mol­ecule, the C4 atom is a chiral centre, but no resolution occurred upon crystal preparation, the racemic mixture crystallizing in the centrosymmetric space group P21/n. The dihedral angle between the planes of the two benzene rings is 80.16 (6)° and the mol­ecular conformation is stabilized by an intra­molecular methyl­ene C5—H⋯O5 hydrogen bond (Table 1[link]).

3. Supra­molecular features

Because of the numerous C=O acceptor groups and the lack of primary donor groups in the mol­ecule, the main inter­molecular inter­actions in the crystal are weak C—H⋯Ocarbox­yl hydrogen bonds (Table 1[link]), having H⋯O distances equal to or less than 2.6 Å. However, one of the four inter­actions (C24—H⋯O8iii; see Table 1[link] for hydrogen-bond geometry details and symmetry codes) involves a nitro O-atom acceptor. Inter­molecular C15—H⋯O7ii hydrogen bonds form centrosymmetric cyclic dimers (Fig. 2[link]) having the graph-set descriptor (Bernstein et al., 1995[Bernstein, J., Davis, R. E., Shimoni, L. & Chang, N. L. (1995). Angew. Chem. Int. Ed. Engl. 34, 1555-1573.]) R22(16). These dimers are linked along the crystallographic a direction through C24—H⋯O8iii hydrogen bonds, forming a chain. These chains are further extended in the crystallographic b direction through C11—H⋯O4i and C12—H⋯O6i inter­actions, forming a cyclic motif with the graph-set descriptor of R22(10) (Fig. 3[link]). Despite the presence of two aromatic rings in the mol­ecule, there are no significant ππ inter­actions in the crystal lattice. This can be explained by the diverse chain system of the mol­ecule and, therefore, the steric preference of the C—H⋯O hydrogen bonds. However, there is a C16—H16⋯π inter­action across c with the C7–C12 nitro­phenyl ring (C⋯Cgiv = 2.81 Å and C—H⋯Cgiv = 149°; Cg is the centroid of the C7–C12 ring) (Fig. 4[link] and Table 1[link]), resulting in an overall three-dimensional supra­molecular structure. The relatively high calculated density (1.367 Mg m−3) and KPI index (Kitaigorodskii packing coefficient = 69.6%) (Spek, 2009[Spek, A. L. (2009). Acta Cryst. D65, 148-155.]) show efficient packing of the mol­ecule, resulting in no residual solvent-accessible voids.

4. Database survey

The structures of different derivatives of 1,2-di­phenyl­pentan-1-one, carrying methyl or nitrile substituents on the chiral C atom, have been reported, viz. Cambridge Structural Database (CSD; Groom & Allen, 2014[Groom, C. R. & Allen, F. H. (2014). Angew. Chem. Int. Ed. 53, 662-671.]) refcodes RULFIN [(S)-4-methyl-4-nitro-1,3-di­phenyl­penta­none; Bakó et al., 1997[Bakó, P., Szöllősy, A., Bombicz, P. & Tőke, L. (1997). Synlett, pp. 291-292.]], DULJOK (1,3-di­phenyl­butan-1-one; Bąkowicz & Turowska-Tyrk, 2010[Bąkowicz, J. & Turowska-Tyrk, I. (2010). Acta Cryst. C66, o29-o32.]) and LAPKEU (4-oxo-2,4-di­phenyl­butano­nitrile; Abdel-Aziz et al., 2012[Abdel-Aziz, A. A.-M., El-Azab, A. S., Ng, S. W. & Tiekink, E. R. T. (2012). Acta Cryst. E68, o736.]). RULFIN and DULJOK crystallized in the chiral P212121 and Pca21 space groups, respectively, and LAPKEU crystallized as a racemic mixture in the centrosymmetric P21/c space group. Comparing the dihedral angles between the planes of the two benzene rings, the steric effect of the bulky substituents on atom C2 can be seen. This value is 62.5° for the methyl derivative (DULJOK) and 68.4° for the nitrile (LAPKEU), but significantly higher for the bulky meth­yl–nitro derivative (88.13°; RULFIN) or the title compound (80.2°).

5. Synthesis and crystallization

The title compound was synthesized by the reaction of 4′-nitro­chalcone [(E)-3-(4-nitro­phen­yl)-1-phenyl­prop-2-en-1-one] with diethyl 2-acet­oxy­malonate. The reaction was carried out in a solid/liquid two-phase system [Na2CO3/tetra­hydro­furan (THF)] in the presence of a gluco­pyran­oside-based crown ether catalyst. The compound was isolated by preparative thin-layer chromatography (TLC) (silica gel) in good yield. The structure of the compound was confirmed by 1H and 13C NMR and mass spectroscopy (m.p. 366–369 K). The details of the synthesis are presented in Rapi et al. (2016[Rapi, Z., Bakó, P., Grün, A., Nemcsók, T., Hessz, D., Kállay, M., Kubinyi, M. & Keglevich, G. (2016). Tetrahedron Asymmetry. In the press.]). Single crystals of the title compound suitable for X-ray diffraction analysis were obtained by crystallization from ethanol.

6. Refinement

Crystal data, data collection and structure refinement details are summarized in Table 2[link]. All H atoms were located in difference electron-density maps. However, these atoms were included in the structure refinement at calculated positions, with C—H = 0.95–1.00 Å, and allowed to ride, with Uiso(H) = 1.2Ueq(C).

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.
