Crystal structure and Hirshfeld surface analysis of 3-({4-[(4-cyano­phen­oxy)carbon­yl]phen­oxy}carbon­yl)phenyl 4-(benz­yloxy)-3-chloro­benzoate

The title compound is a non-liquid crystal with a bent-shaped mol­ecule in which adjacent aromatic rings are close to perpendicular to each other.

Abstract

The title compound, C₃₅H₂₂ClNO₇, is a non-liquid crystal with a bent-shaped mol­ecule. The dihedral angles between adjacent aromatic rings in the mol­ecule (starting from the cyano­benzene ring) are 72.61 (2), 87.69 (4), 64.08 (2) and 88.23 (2)°, indicating that adjacent rings are close to perpendicular to each other. In the crystal, the mol­ecules are linked by weak C—H⋯N and C—H⋯π inter­actions, thereby forming a two-dimensional supra­molecular architecture in the ac plane. The most important contributions to the crystal packing arise from H⋯H (59.3%), S⋯H (27.4%) and O⋯H (7.5%) inter­actions, as determined by a Hirshfeld surface analysis.

1. Chemical context

Banana/bent-shaped liquid crystals (LCs) are of great inter­est in the field of display materials. In particular, the –CN groups at the terminal end (Walba et al., 2000 ▸; Reddy & Sadashiva, 2004 ▸) of banana-shaped LCs have been linked to their bent or bow (twisted) anisometric phase with C _2v symmetry. Furthermore, they exhibit polar order, chirality and spontaneous polarization in the fluid phase. We have reported the crystal structures of LC inter­mediates and found that benz­yloxy group-substituted mol­ecules are prone to be hydro­phobic (Kashi et al., 2012 ▸; Al-Eryani et al., 2011 ▸). Benz­yloxy group-substituted mol­ecules also play a significant role in synthesizing bent-shaped LCs and non-LCs (Palakshamurthy et al., 2012 ▸). Hence, it is useful to study benz­yloxy group-substituted bent-shaped mol­ecules to understand the structural properties and the relationship between LCs and crystal structures.

In a continuation of this work, we investigated the title mol­ecule, which possesses five aromatic rings with three ester groups and a benz­yloxy group at one terminal end, presumably making the mol­ecule highly polar. Furthermore, it has a chloro group at one side and a cyano group at the opposite terminal end of the mol­ecule, inducing an unsymmetrical structure (Hartung et al., 2000 ▸). The mol­ecule was subjected to LC characterization studies, but it did not show any LC properties, which may be due to the absence of a flexible alkyl chain. The title compound was synthesized according to the procedure described by Sadashiva et al. (2002 ▸) and its crystal structure is reported herein.

2. Structural commentary

The mol­ecular structure of the title compound is shown in Fig. 1 ▸. The dihedral angles between the aromatic rings are as follows: A/B = 64.08 (2), A/C= 29.75 (2), A/D = 87.69 (4), A/E = 16.07 (3), B/C = 88.23 (2), B/D = 87.88 (4), B/E = 68.87 (4), C/D = 82.27 (3), E/D = 72.61 (2) and C/E = 37.46 (4)°, where A, B, C, D and E are the C1–C6, C23–C28, C30–C35, C8–C13 and C15–C20, rings, respectively. The torsion angles associated with the benz­yloxy group are −7.2 (3) (C15—O4—C14—O3), −3.1 (3) (C8—O2—C7—O1) and −0.7 (2)° (C3—O6—C22—O5). Three short intra­molecular C—H⋯O contacts (Table 1 ▸) may influence the mol­ecular conformation.

3. Supra­molecular features

In the crystal, the mol­ecules are linked by weak C—H⋯N hydrogen bonds and weak C—H⋯π inter­actions (Table 1 ▸) to generate a two-dimensional supra­molecular architecture propagating in the ac plane as shown in Fig. 2 ▸. Furthermore, the mol­ecules are linked by centrosymmetric aromatic π–π stacking inter­actions with Cg4⋯Cg4 and Cg3⋯Cg3 = 3.6387 (10) Å (slippage = 1.086 Å) and 3.7740 (10) (slippage = 1.407 Å), respectively, as shown in Fig. 3 ▸ (Cg4 is the centroid of the C23–C28 ring and Cg3 is the centroid of the C15–C20 ring).

4. Database survey

A search of the Cambridge Structural Database (CSD, version 5.42, update of November 2020; Groom et al., 2016 ▸) for mol­ecules containing the (4-cyano­phen­oxy)carbonyl fragment resulted in four matches with CSD refcodes EWUSIA (Srinivasa et al., 2015 ▸), IBUXOV (Ji et al., 2017 ▸), IBUXUB (Yingchun et al., 2016 ▸) and OCUTIS (Yingchun et al., 2016 ▸). In all these structures there is a 4-cyano­phen­oxy grouping at the one end of the mol­ecule, similar to the title compound. In IBUXOV, IBUXUB and OCUTIS the same core exists at both ends of the mol­ecule. Sometimes the presence of a –CN group at both terminals of the mol­ecule induces liquid-crystal properties.

In EWUSIA, the dihedral angles between the cyano­benzoate ring and the first neighbouring benzene ring, and between the second neighbour and the first and second benzene rings are 50.47 (2), 10.15 (3) and 50.02 (5)° compared to 72.61 (2), 16.06 (2) and 87.69 (4)° in the title mol­ecule. In IBUXOV, the dihedral angles between the rings (cyano­benzoate ring and the neighbouring benzene ring) are 69.45 (2) and 64.20 (3)°, and 73.60 (3) and 84.16 (3)° between the adjacent cyano­benzoate and benzene rings themselves. In IBUXUB, the dihedral angles between the rings (cyano­benzoate and the neighbouring benzene ring) are 69.68 (2) and 74.28 (4)°, and 48.87 (2) and 89.88 (4)° between the cyano­benzoate and benzene rings. In OCUTIS, the dihedral angles between adjacent cyano­benzoate and benzene rings are 81.21 (4) and 54.43 (2)° compared to angles between the cyano­benzoate and benzene rings of 55.02 (3) and 84.20 (3)°.

5. Hirshfeld surface analysis

CrystalExplorer17.5 (Turner et al., 2017 ▸) was used to perform the Hirshfeld surface analysis (Spackman & Jayatilaka, 2009 ▸) to further qu­antify the various inter­molecular inter­actions. The Hirshfeld surface mapped over d _norm is illustrated in Fig. 4 ▸ and the associated two-dimensional fingerprint plots in Fig. 5 ▸. The major contributions to the crystal structure are from H⋯H (26.9%), C⋯H (27.2%) and O⋯H (19.6%) contacts. In Figs. 6 ▸ and 7 ▸, the red spots on the d _norm and d _e surfaces represent the C—H⋯π inter­actions.

6. Synthesis and crystallization

4-[(4-Cyano­phen­oxy)carbon­yl]phenyl 3-hy­droxy­benzoate (1 mmol) and 4-(benz­yloxy)-3-chloro­benzoic acid (1.2 mmol) were dissolved in dry chloro­form (50 ml). After the addition of N,N-di­cyclo­hexyl­carbodi­imide (1.2 mmol) and a catalytic amount of 4-(N,N-di­methyl­amino)­pyridine (DMAP), the mixture was stirred at room temperature for about 12 h. The di­cyclo­hexyl­urea that precipitated was filtered off and the filtrate diluted with chloro­form. This solution was washed with 2% aqueous acetic acid solution (10 ml) and 5% ice-cold sodium hydroxide solution (10 ml) and finally washed with water and dried over anhydrous sodium sulfate. The crude residue obtained was chromatographed on silica gel using chloro­form as an eluent. Removal of solvent from the eluate afforded the white target material, which was crystallized from a mixture of chloro­form and aceto­nitrile. Single crystals in the form of colourless prisms suitable for diffraction studies were grown from a solution in ethyl alcohol by slow evaporation.

Special details

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.
