In the title compound, C36H24Br3N3O6·C7H8, the toluene solvent molecule is associated with the receptor molecule via C—H⋯π bonding. The planes of the phthalimido groups are inclined at 77.0 (1), 63.0 (1) and 77.8 (1)° with respect to the benzene ring. The molecular conformation is stabilized by C—H⋯O and C—H⋯Br hydrogen bonds. The features non-classical hydrogen bonds of the C—H⋯N, C—H⋯O and C—H⋯Br type, leading to a three-dimensional cross-linking of molecules. The pattern of non-covalent intermolecular bonding is completed by O⋯Br halogen bonds [3.306 (3) Å], which link the receptor molecules into infinite strands extending along the a-axis direction.

The synthesis of the title compound was carried out in a slightly modified literature procedure (Roelens et al. 2009). 1,3,5-Tris(phthalimidomethyl)-2,4,6-trimethylbenzene (1.00 g, 1.67 mmol) was dissolved in 1,2-dibromoethane (20 ml) and bromine (0.28 ml, 5.50 mmol) was added. The reaction mixture was stirred for overall 48 h under reflux and irradiation with a halogen bulb (500 W); after 24 h an additional amount of bromine (0.28 ml, 5.50 mmol) was added. The reaction mixture was cooled and washed with saturated aqueous solutions of sodium metabisulfite (2 x 20 ml), sodium bicarbonate (20 ml), and distilled water (20 ml). The organic phase was dried over sodium sulfate and the solvent removed by distillation. The residue was purified by δ 7.87–7.77 (m, 6H, aryl), 7.75–7.67 (m, 6H, aryl), 5.10 (s, 12H CH2); 13C NMR (100 MHz, CDCl3) δ 29.26, 36.40, 123.48, 132.03, 134.18, 134.87, 140.32, 168.28; EI—MS (70 eV) m/z: 595, 675, 754.

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. |
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. |

Our interest in the title compound, C36H24N3O6Br3, arises from its use as a precursor in the synthesis of novel heteroditopic artificial receptors containing a hexasubstituted benzene scaffold. The synthesis of ditopic receptors, which interact simultaneously with cationic and anionic guests in so called ion-pair recognition processes, is a rapidly developing area of research (McConnell & Beer, 2012). A number of ditopic receptors based on a macrocylic or acyclic scaffold have been designed and studied (Kinnear et al. (1994), Kirkovits et al. (2001), Hossain & Schneider (1998), Tsukube et al. (1999) and Smith (2010)) Interesting applications, such as binding of amino acids in their zwitterionic state, salt extraction and membrane transport, have been reported in the literature (for a recent review, see McConnell & Beer, 2012). In this context, the title compound is a particularly useful building block for the construction of a large number of receptors with different recognition units, because it provides a base for many synthetic modifications of the molecule structure. Crystallization of the title compound from toluene yields a 1:1 solvent complex (Fig. 1). According to the three-dimensional arrangement of the substituent groups around the periphery of the central arene ring, the conformational isomer of the receptor can be described as 1-down, 3,5-up tris((phthalimidomethyl), 2,4-down, 6-up tris(bromomethyl)benzene. The mean planes of the phthalimido moieties are inclined at angles of 77.0 (1), 63.0 (1) and 77.8 (1)° with reference to the plane of the benzene ring. The torsion angles given by the atomic sequences C1—C2—C7—Br1, C3—C4—C8—Br2 and C5—C6—C9—Br3 are 93.3 (2), 92.5 (2) and -99.8 (2) °, respectively. The host lattice is stabilized by non-conventional hydrogen bonds of the C—H···N [d(H···N) 2.55 Å], C—H···O [d(H···O) 2.18–2.58 Å] and C—H···Br type [d(H···Br) 2.77, 2.89 Å]. Moreover, the intermolecular distance O1···Br2 [3.306 (3) Å], which is less than the sum of van der Waals radii of the respective atoms [3.37 Å], indicates the presence of a weak C=O···Br halogen bond. As depicted in Fig. 2, the interactions between the receptor and the solvent molecule are reduced to weak C—H···π contacts with the aromatic ring of the toluene molecule and one of the phthalimido units of the receptor acting as acceptors [C22—H22···cg1 2.66 Å, 169 °, C6A—H6A···cg2 2.99 Å, 143 °]. Taking into account this kind of interactions, the crystal structure can be regarded as being composed of infinite strands of 1:1 complex units running along the crystallographic a-axis (Fig. 3).
