Monomolecular sheets of propeller-shaped triethyl 4,4',4''-[benzene-1,3,5-triyltris(ethyne-2,1-di­yl)]tribenzoate deuterochloroform monosolvate

The title compound, C₃₉H₃₀O₆·CDCl₃, has a chemical threefold axis and an approximately planar structure, with an eth­oxy­carbonyl substituent on each of the terminal benzenes oriented in the same direction, thus forming a propeller-shaped mol­ecule. This mol­ecule is of particular inter­est in the field of metal-organic frameworks (MOFs), where its hydrolyzed analogue forms MOF structures with high surface areas. The benzene ring which occupies the centre of the mol­ecule forms [pi]-[pi] inter­actions to the equivalent benzene ring at a perpendicular distance of 3.32 (1) Å. Centrosymmetric dimers formed in this way are inter­connected by inter­molecular C-H...[pi] inter­actions with a rather short H...CgA distance of 2.51 Å (CgA is the centroid of the central benzene ring). The mol­ecules are arranged in regular parallel sheets. Within a sheet, mol­ecules are inter­connected via C-H...O inter­actions where all carbonyl O atoms participate in weak hydrogen bonds as hydrogen-bond acceptors. Neighbouring sheets are connected through the above-mentioned [pi]-[pi] and C-H...[pi] inter­actions.

S1. Introduction

Symmetrical substituted benzenes have found widespread application as building units for the construction of attractive new metal–organic framework (MOF) structures (Kim et al., 2001; Hee et al., 2004; Kozachuk et al., 2014). In particular 4,4',4''-[benzene-1,3,5-triyltris(ethyne-2,1-diyl)]tribenzoate [benzoic acid?], which can be readily obtained by the hydrolysis of the herein reported triester, have been recently shown to produce MOF structures (MOF-180 and MOF-210; Furukawa et al., 2010) with surface areas up to 10400 m² g^-1. These materials exhibit exceptional porosities and gas (hydrogen, methane and carbon dioxide) uptake capacities. Analogous planar symmetrical benzene-based molecules have also sparked inter­est in the construction of new functional materials due to their adsorption on flat gold or graphite surfaces (Gutzler et al., 2009; Dienstmaier et al., 2010; Madueno et al., 2008). Clearly the structure of the title molecule is of inter­est in a variety of emerging research areas, and even though the organic backbones of MOFs have been structurally characterized, we report here the first crystal structure of the tri­ethyl ester building block tri­ethyl 4,4',4''-[benzene-1,3,5-triyltris(ethyne-2,1-diyl)]tribenzoate, (I).

S2. Experimental

S2.1. Synthesis and crystallization

Copper(I) iodide, 1,3,5-tri­bromo­benzene and dichloridobis(tri­phenyl­phosphane)palladium were commercially available (Aldrich). 1,3,5-Triethynyl­benzene (Demessence et al., 2009) and the title compound (Castellano & Rebek, 1998; Kuroda et al., 2006) were synthesized according to slight modifications of published procedures. Solid 1,3,5-tri­bromo­benzene (9.45 g, 30.00 mmol), copper(I) iodide (50 mg, 0.26 mmol) and dichloridobis(tri­phenyl­phosphane)palladium(II) (400 mg, 0.57 mmol) were dissolved in freshly distilled tri­ethyl­amine (200 ml) under a nitro­gen atmosphere. Trimethysilyl­acetyl­ene (10.6 g, 108 mmol) was added and the mixture was heated at 323 K for 24 h. After cooling, the resulting precipitate of tri­ethyl­amine hydro­bromide was removed by filtration and washed with ether. The combined filtrates were evaporated to dryness under reduced pressure and the residue was chromatographed on a column (SiO₂, hexane) to yield 9.4 g (87%) of 1,3,5-tris­(tri­methyl­silylethynyl)benzene. Aqueous NaOH (1 M, 50 ml) was then added to a solution of tris­(tri­methyl­silylethynyl)benzene (315.6 mg, 0.862 mmol) in ethanol (80 ml), and the reaction mixture was heated with stirring at 313 K for 12 h. The solvent was evaporated and the residue was extracted with di­ethyl ether. The organic layer was dried over anhydrous magnesium sulfate and evaporated to dryness to yield the product. Crude 1,3,5-triethynyl­benzene (123 mg, 0.82 mmol) was dissolved in dry tri­ethyl­amine (40 ml) and added to a Schlenk flask containing ethyl 4-bromo­benzoate (751 mg, 3.28 mmol), dichloridobis(tri­phenyl­phosphane)palladium(II) (70 mg, 0.1 mmol) and cuprous iodide (19 mg, 0.1 mmol). The reaction mixture was degassed and then stirred at 323 K for 3 d. The solution was evaporated and the residue was dissolved in ethyl acetate, washed with water and the organic layer was dried with anhydrous magnesium sulfate. The solvent was removed by evaporation and the residue was subjected to chromatography on silica gel with ethyl acetate/hexane (1:6) as the eluent to yield the product (yield 70 mg, 0.118 mmol, 14.4%). Single crystals of (I) were obtained by slow evaporation from a CDCl₃ solution.

S2.2. Refinement

Crystal data, data collection and structure refinement details are summarized in Table 1. H atoms bonded to C atoms were placed at calculated positions, with C—H distances fixed at 0.93 Å for aromatic, and at 0.96 and 0.97 Å for methyl and methyl­ene C atoms. The corresponding isotropic displacement parameters of H atoms were set equal to 1.2U_eq of the parent aromatic and methyl­ene, and at 1.5U_eq of the methyl C atoms.

The deuterium atom from the deuterated solvent solvent molecule, CDCl₃, was located in a difference Fourier map and was refined isotropically. H and D atoms were included in the SFAC and UNIT instructions separately, while both atom types employed the `H' scattering factor number.

S3. Comment

The molecule of (I) (Fig. 1) is almost planar and has a chemical threefold axis. However, the three terminal benzene rings [B (atoms C9–C14), C (atoms C20–C25) and D (atoms C31–C36)] have slightly different orientations with respect to to the central ring A (atoms C1–C6). The planes of rings C and A exhibit the largest dihedral angle [7.3 (1)°], while the planes of rings B and D are almost coplanar with that of the central ring [dihedral angles = 3.1 (1) and 2.5 (1)°, respectively]. Bond lengths and angles (Table 2) are very similar for all three aromatic fragments in (I).

Each of the three pendent benzene rings is substituted by an eth­oxy­carbonyl group in the para position. The orientation of this substituent is the same in all three cases giving rise to a propeller-shaped molecule. Also in these ethyl ester groups, all non-H atoms are essentially coplanar (r.m.s. deviation of fitted atoms = 0.034, 0.017 and 0.007 Å for B, C and D, respectively). The dihedral angle between the mean plane through the eth­oxy­carbonyl group and the attached aromatic ring varies from 13.0 (2)° for ring B to 6.6 (2)° for ring D ring and 1.6 (2)° for ring C. Ring B exhibits the largest deviation of the eth­oxy­carbonyl group from coplanarity with the aromatic ring; a possible explanation for this structural difference can be found in the fact that ring B forms a C—H···O hydrogen bond to the CDCl₃ solvent molecule. Considering the H···O distance as a criterion, this hydrogen bond (C40—D40···O1; symmetry code: x, y+1, z) is the most important hydrogen bond in the structure of (I) (Table 3). All carbonyl O atoms in (I) participate in weak C—H···O hydrogen bonds with neighboring molecules in the same layer, but the H···O distances in all cases are longer than 2.50 Å (Table 3).

The central benzene ring plays a significant role in the crystal packing of (I). This ring forms the most important π–π stacking inter­action, with a perpendicular inter­planar distance to the neighboring ring Aⁱ at [symmetry code: (i) -x+1, -y+1, -z+1] of 3.32 (1) Å [the distance between the centroids (Cg) of the two rings is 3.549 (1) Å]. The centrosymmetric dimer formed via this inter­molecular inter­action is shown in Fig. 2. Within the dimer, atom C5 is almost perfectly located above the centroid of the neighboring ring (C5···CgA = 3.35 Å), while atoms C1 and C3 are positioned approximately one above the other, with a C1···C3ⁱ distance of 3.362 (3) Å. Besides the π–π inter­actions, ring A also participates in a relatively strong C—H···π inter­molecular inter­action as π-acceptor of the C27 methyl­ene group. Atom H27B bonded to C27 is directed towards the centroid of ring A, forming a rather short H···CgA distance of 2.64 Å [perpendicular distance of H27B to ring A is 2.62 Å and the C27—H27B···CgA angle is 157°).

When the C27—H27B distance is corrected to a standard distance of ca 1.10 Å the H27B···CgA distance becomes 2.53 Å (orthogonal distance = 2.51 Å) which qualifies this inter­action as a relatively strong inter­molecular C—H···π inter­action (Desiraju & Steiner, 2001). Molecules of (I) form parallel sheets in the crystal packing. Within a sheet, molecules are inter­connected by C—H···O hydrogen bonds (see Table 3 for geometrical parameters and Fig. 3 for illustration), while the molecules in parallel neighbouring layers are inter­connected by the above-described π–π and C—H···π inter­actions formed by ring A (Fig. 4). Ring C also participates in π–π inter­actions between sheets [CgC···CgCⁱⁱ = 3.781 (1) Å; symmetry code: (ii) -x+1, -y, -z+1, while the perpendicular inter­planar distance between two C rings is 3.50 (1) Å].

In the Cambridge Structural Database (Allen, 2002), we found only five crystal structures with organic molecules having the same aromatic core as molecule (I) [see structure (II) in the Scheme]: OCUKEC (Day et al., 2001); PUBDOF (Bochkarev et al., 1998); PUBDOF01, WEVYIF and WEVYOL (Ponzini et al., 2000); ZABQUO and ZABQUO01 (Gardner et al., 1995). Unfortunately, the early crystal structures (refcodes ZABQUO and ZABQUO01) are without atomic coordinates. Nevertheless, a brief comparison of geometrical parameters and accessible information for all crystal structures confirms very similar bond distances within fragment (II), while some conformational characteristics (such as mutual orientation of terminal and central benzene rings) were found to differ significantly. Only in WEVYIF were all three terminal benzene rings approximately coplanar with the central ring (dihedral angles = 2.5–9.1°). This crystal structure is also the only case where structures form parallel layers similar to that observed in the crystal packing of (I). The central ring forms π–π inter­actions to a neighbouring central ring in OCUKEC and WEVYIF, while in no case does this ring participate as a π-acceptor in C—H···π inter­actions.

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.
