Abstract

The title compounds, C₂₃H₂₅Br₂NO₂ (1) and C₃₁H₂₉BrN₂O₄ (2), crystallize in the space group P2₁/n with two (1-A and 1-B) and one mol­ecules, respectively, in the asymmetric unit of the cell. The mol­ecular conformation of these compounds is stabilized by intra­molecular C—H⋯O hydrogen bonds and C—H⋯N or C—H⋯π inter­actions. The crystal structure of 1 features a relatively strong Br⋯O=C halogen bond, which is not observed in the case of 2. Both crystal structures are characterized by the presence of C—H⋯Br hydrogen bonds and numerous inter­molecular C—H⋯O hydrogen-bonding inter­actions.

Chemical context  

Compounds consisting of a 1,3,5-tris­ubstituted 2,4,6-tri­alkyl­benzene scaffold have been recognized to possess the ability to act as artificial receptors for various neutral and ionic substrates, such as carbohydrates (Mazik, 2009 ▸, 2012 ▸), ion pairs (for example, hydro­nium/hydroxide ions; Stapf et al., 2015 ▸) and ammonium ions (Chin et al., 2002 ▸; Jonah et al., 2017 ▸; Schulze et al., 2018 ▸). In the case of carbohydrate-binding agents (artificial carbohydrate receptors), both acyclic (Kaiser et al. 2019 ▸; Stapf et al., 2020a ▸, 2020b ▸; Köhler et al., 2020 ▸) and macrocyclic compounds (Lippe & Mazik, 2013 ▸, 2015 ▸; Amrhein et al., 2016 ▸; Amrhein & Mazik, 2021 ▸) have been developed. Bromo­methyl- and/or phthalimidomethyl-functionalized tri­alkyl­benzenes are often used as precursors for the syntheses of such compounds . The crystal structures of two representatives of this class of compounds bearing both bromo­methyl- and phthalimidomethyl groups are described in this work.

Structural commentary  

Compounds 1 and 2, the structures of which are illustrated in Fig. 1 ▸, were found to crystallize in the monoclinic space group P2₁/n. In the case of compound 1, the asymmetric unit of the cell consists of two crystallographically non-equivalent mol­ecules (1-A and 1-B). Mol­ecule 1-A displays a conformation with a fully alternating arrangement of the substituents above and below the plane of the central benzene ring [ab′ab′ab′ pattern, a = above, b = below (a′/b′ = Et above/below); see Koch et al., 2017 ▸; Schulze et al., 2017 ▸]. In mol­ecule 1-B, one of the ethyl groups is disordered over two positions with an occupancy of 0.820 (6) for the major disorder component; the two disorder positions are related by rotation of approximately 180° about the C4—C11 bond. The mol­ecules display similar conformations, as illustrated by the mol­ecular least-squares overlay shown in Fig. 2 ▸. The dihedral angle between the phthalimide moiety and the benzene ring is 82.27 (14)° (mol­ecule 1-A) and 83.78 (13)° (mol­ecule 1-B). The conformation of the mol­ecules appear to be stabilized by intra­molecular C—H⋯O=C hydrogen bonds (Tables 1 ▸ and 2 ▸), which involve ethyl H atoms [d(H⋯O) = 2.59, 2.64 Å]. Furthermore, one ethyl group of each mol­ecule participates in the formation of an intra­molecular C—H⋯N bond with H⋯N distances of 2.45 and 2.54 Å, respectively.

The crystal structure of compound 2 contains one mol­ecule in the asymmetric unit of the cell. The two phthalimide groups of the mol­ecule point in opposite directions, showing inclination angles of 70.27 (16) and 79.10 (16)° with respect to the plane of the central aromatic ring. The three-dimensional arrangement of substituents along the periphery of the benzene ring follows an ab′ba′ab′ pattern, in which the bromo­methyl group, one phthalimidomethyl unit and one ethyl group are directed towards one face of the benzene ring, whereas the three remaining substituents point in the opposite direction. This conformation is stabilized by intra­molecular C_eth­yl—H⋯O=C (2.45, 2.50 Å) and C_eth­yl—H⋯π inter­actions [d(H⋯Cg) 2.80, 2.85 Å].

Supra­molecular features  

In the crystal of compound 1, the distance of 3.220 (3) Å between Br2B and the oxygen atom O1A of an adjacent mol­ecules (symmetry code: 1 + x, y, z) is considerably shorter than the sum of the van der Waals radii of the atoms (3.37 Å; Bondi, 1964 ▸); this, as well as the well-defined bond geometry [∠C—Br⋯O = 171.34 (11)°] indicates the presence of a relatively strong Br⋯O halogen bond (Table 3 ▸). This C—Br⋯O=C inter­action is assisted by a C—H⋯Br bond [d(H⋯Br) = 2.92 Å, ∠C—H⋯Br = 141.6°], so that atom Br2B acts as a bifurcated binding site (see Fig. 3 ▸). The atoms Br1B and Br2A are involved in the formation of C_eth­yl—H⋯Br inter­actions with distances of 2.86 and 3.00 Å, respectively (∠C—H⋯Br = 123 and 158°). The two independent mol­ecules are involved in a different way in the mol­ecular association. The phthalimide group of mol­ecule 1-B participates in the formation of C—H⋯π contacts with H⋯Cg distances of 2.62 and 2.96 Å, whereas the phthalimide moiety of the second mol­ecule is involved in the formation of an offset face-to-face inter­action [d(Cg⋯Cg) = 3.75 Å, symmetry code: −x, 1 − y, 1 − z]. In addition, the crystal packing is characterized by the presence of several C—H⋯O hydrogen bonds (2.35–2.43 Å; Table 1 ▸). The different types of non-covalent bonds in the crystal generate a three-dimensional supra­molecular network.

As a result of the presence of two phthalimide units in compound 2, its crystal structure is dominated by C—H⋯O bonds [d(H⋯O) = 2.49–2.59 Å; Table 2 ▸] in which all oxygen atoms participate. The fragment of the packing structure shown in Fig. 4 ▸ shows that atoms O1 and H10A take part in the formation of an inversion-symmetric supra­molecular ring motif with graph-set motif (10) (Etter, 1990 ▸; Bernstein et al., 1995 ▸; such a ten-membered supra­molecular motif has, for example, been recognized in some crystal structures of fluorene derivatives bearing phthalimidomethyl groups, see Seidel et al., 2021 ▸). In addition, the mol­ecules are linked by two C—H⋯π inter­actions [d(H⋯Cg = 2.84, 2.88 Å] with the C1–C6 and C12–C17 rings acting as acceptors.

Database survey  

A search in the Cambridge Structural Database (CSD, Version 5.41, update of November 2019; Groom et al., 2016 ▸) for 2-benzyl­isoindoline-1,3-dione resulted in 48 hits. Regarding the description of crystal structures of tri- to hexa­substituted benzene derivatives, the number of hits could be reduced to three relevant entries. This includes two hexa­substituted benzene derivatives consisting of three isoindoline-1,3-dione groups (phthalimidomethyl groups) and either meth­oxy (IDOBIO; Rosien et al., 2013 ▸) or bromo­methyl groups (LOFBIT; Koch et al., 2014 ▸) in each of the 2-, 4- and 6-positions of the benzene ring. Furthermore, a 1,3,5-tris­ubstituted benzene derivative, namely 3,5-bis­(phthalimidometh­yl)phenyl-tert-butyl­dimethyl­silyl ether (WIKRAK; Domínguez et al., 2007 ▸), has been found. In the case of IDOBIO and LOFBIT, the mol­ecules adopt a conformation in which two phthalimidomethyl groups and one meth­oxy or bromo­methyl group are directed towards one face of the benzene ring. The phthalimidomethyl groups of the 1,3,5-tris­ubstituted benzene derivative adopt a trans geometry.

Synthesis and crystallization  

A suspension of 1,3,5-tris­(bromo­meth­yl)-2,4,6-tri­ethyl­benzene (1.00 g, 2.27 mmol) and potassium phthalimide (0.84 g, 4.54 mmol) in a solvent mixture N,N-di­methyl­formamide/1,4-dioxane (15 ml, 2:1, v/v) was stirred at ambient temperature for 24 h. Afterwards, the reaction mixture was poured into 50 ml of water. The white precipitate was filtered off, washed several times with water and finally suspended in water. After extraction with chloro­form (five times) and evaporation of the organic solvent, the crude product was purified by column chromatography (SiO₂; toluene/ethyl acetate). Compounds 1 and 2 were obtained as white solids.

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.

2-{5-(Bromomethyl)-3-[(1,3-dioxoisoindolin-2-yl)methyl]-2,4,6-triethylbenzyl}isoindoline-1,3-dione (2). 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.
