Synthesis and crystal structure of anti-10-(4-cyano­phen­yl)-10,11,22,23-tetra­hydro-9H,21H-5,8:15,12-bis­(metheno)[1,5,11]tri­aza­cyclo­hexadecino[1,16-a:5,6-a′]di­indole di­chloro­methane monosolvate

The title compound consists of one anti-4-(1⁹H,5⁹H-3-aza-1,5(3,9)-dicarbazola­cyclo­octa­phane-3-yl)benzo­nitrile (host mol­ecule) and one di­chloro­methane solvate mol­ecule. The host mol­ecule adopts an anti configuration, in which two carbazole rings are partially overlapped, forming an intra­molecular π–π inter­action. In the crystal, the mol­ecules are cross-linked via inter­molecular host–host and host–guest C—H⋯π inter­actions, forming a three-dimensional network.

Abstract

The asymmetric unit of the title compound is composed of one host mol­ecule, anti-4-(1⁹H,5⁹H-3-aza-1,5(3,9)-dicarbazola­cyclo­octa­phane-3-yl)benzo­nitrile and one di­chloro­methane solvate mol­ecule, C₃₆H₂₈N₄·CH₂Cl₂. The host mol­ecule possesses a planar chirality but crystallizes as a racemate in the space group P2₁/c. It adopts an anti-configuration, in which two carbazole rings are partially overlapped with a parallel orientation. The two carbazole ring systems are slightly bent, and the C atoms at the 3- and 1-positions show the largest deviations from the mean planes. The dihedral angle between two carbazole rings is 9.42 (3)°, forming an intra­molecular parallel π–π inter­action [Cg⋯Cg = 3.2755 (9) Å]. In the crystal, the mol­ecules are linked via host–host and host–guest C—H⋯π inter­actions, forming chain structures along the a-axis direction. The mol­ecules are linked into a ribbon structure along the c-axis direction by further C—H⋯π inter­actions. As a result, The mol­ecules are cross-linked by C—H⋯π inter­actions into a three-dimensional network.

1. Chemical context

Many carbazole derivatives emit blue fluorescence in good quantum yields, and have been used in the development of organic light-emitting diodes (Chen et al., 2021 ▸). The carbazole chromophore, which shows donor character, has been employed as a hole-transporting material in organic solar cells (Konidena et al., 2022 ▸). As for the structure of the excimer in carbazole chromophore, partially overlapped (PO) and fully overlapped (FO) excimers were proposed (Sakai et al., 1996 ▸). To investigate the structure and photophysical properties of the carbazole excimer, our group has synthesized various carbazolophanes (CZPs), which are cyclo­phanes composed of two carbazole rings (Tani et al., 1996 ▸; Benten et al., 2005 ▸). The framework of [3.3](3,9)- and [3.4](3,9)-CZPs, where (3,9) describes the bridging position of carbazole ring, and [m.n] denotes the number of bridging lengths between the 3- and 9-positions, are rigid enough to isolate both PO (anti) and FO (syn) isomers at room temperature. For [3.3](3,9)-CZPs, flipping of the carbazole ring between syn and anti CZPs does not occur at room temperature, therefore anti CZPs with planar chirality were successfully separated as enanti­omers (Tani et al., 2020 ▸). Intriguingly, the fluorescence spectrum of cyanamide-bridged [3.3](3,9)-CZP was assigned to be excimeric emission, while monomer-like emission was observed in [3.4](3,9)-CZP (Tani et al., 2007 ▸). This result indicates that excimer formation in the carbazole chromophore is extremely susceptible to the geometry of the two carbazole rings in close proximity. As the [3.3](3,9)-aza-bridged CZPs synthesized so far were N-sulfonamide-bridged CZP (Tani et al., 2020 ▸), N-cyanamide-bridged CZP (Tani et al., 2001 ▸), and N-n-butyl­amine-bridged CZP (Kubono et al., 2022 ▸), we plan to synthesize more basic aromatic amine-bridged CZP, that is, an aniline derivative-bridged one, which is a potential candidate for systematic elucidation of the excimer formation in the carbazole chromophore. 4-Cyano­aniline was chosen to begin this research since it is treated as the insertion of phenyl­ene moiety into cyanamide and the effect of the aromatic ring can be evaluated. The cyclization reaction between 4-cyano­aniline and 9,9-(1,3-propanedi­yl)-bis­[3-(bromo­meth­yl)-9H-carb­azole] gave the title com­pound, anti-10-(4-cyano­phen­yl)-10,11,22,23-tetra­hydro-9H,21H-5,8:15,12-bis­(metheno)[1,5,11]tri­aza­cyclo­hexa­decino[1,16-a:5,6a′]di­indole[cyclo­phane nomenclature: anti-4-(1⁹H,5⁹H-3-aza-1,5(3,9)-dicarb­azola­cyclo­octaphane-3-yl)ben­zo­nitrile] di­chloro­methane solvate. Herein we report on the synthesis and crystal structure of it.

2. Structural commentary

The asymmetric unit of the title compound is composed of one host mol­ecule and one di­chloro­methane solvate mol­ecule (Fig. 1 ▸). The host mol­ecule of the title compound possesses a planar chirality but crystallizes as a racemate in the centrosymmetric space group P2₁/c. The host mol­ecule adopts an anti-configuration with parallel orientation, thus it is classified into a PO-CZP structure. The carbazole ring systems are slightly bent, with r.m.s. deviations of 0.066 (1) and 0.078 (1) Å, respectively, for the N3/C7–C18 ring and N4/C19–C30 ring systems. In two carbazole fragments, the C atoms at the 3- and 1-positions of carbazole ring show the largest deviations from mean planes [−0.1174 (15) Å for C10 (3-position) and −0.1219 (14) Å for C24 (1-position)]. The dihedral angle between two carbazole fragments is 9.42 (3)°, providing an intra­molecular π–π inter­action [Cg3⋯Cg4 = 3.2755 (9) Å; Cg3 and Cg4 are the centroids of rings C7–C12 and C19–C24, respectively]. In comparison, the dihedral angle between the two carbazole rings and Cg⋯Cg distances in the crystal structures of related compounds are 5.19 (3)° and 3.2514 (8) Å for [3.3](3,9)-N-n-butyl­amine-bridged PO-CZP (XEBDAN; Kubono et al., 2022 ▸) and 9.65 (5)° and 3.2296 (12) Å for [3.3](3,9)-N-(R)-phenethyl­amine-bridged (S_p)-PO-CZP (YOLRAW; Tani et al., 2023 ▸), which are close to those of the host mol­ecule in the title compound. The bond angle C34—N5—C35 is 114.81 (11)° in the title compound, similar to those of the related compounds [114.56 (11)° for XEBDAN; 113.97 (16)° for YOLRAW]. For the related compound with a cyano­aniline moiety, 4-(di­benzyl­amino)­benzo­nitrile, the average C(methyl­ene)—N—C bond angle in the two independent mol­ecules in the crystal (IYAXOY; Luo et al., 2021 ▸) is 115.97 (12)°. The N5 atom is located 0.0067 (11) Å above the mean plane of the three bounded carbon atoms (C34/C35/C36) in the tertiary amino group. The N5 atom has highly sp² orbital character because this bridged amine contains an aromatic moiety, whose nitrile group in the 4-position is an electron-withdrawing one.

3. Supra­molecular features

In the crystal, two mol­ecules are associated through a pair of inter­molecular C—H⋯π inter­actions [C33—H33A⋯Cg2ⁱⁱ; H33A⋯Cg2ⁱⁱ = 2.91 Å; C33⋯Cg2ⁱⁱ = 3.6402 (17)Å; Cg2 is the centroid of the C13–C18 ring, symmetry code: (ii) 1 − x, 1 − y, 1 − z] (Table 1 ▸), forming a centrosymmetric dimer. The dimers and solvate di­chloro­methane mol­ecules are linked by two other C—H⋯π inter­actions [C43—H43A⋯Cg3ⁱⁱⁱ; H43A⋯Cg3ⁱⁱⁱ = 2.56 Å; C43⋯Cg3ⁱⁱⁱ = 3.4632 (17) Å, and C43—H43B⋯Cg4; H43B⋯Cg4 = 2.54 Å; C43⋯Cg4 = 3.4277 (17) Å; Cg3 and Cg4 are the centroids of the C7–C12 and C19–C24 rings, respectively; symmetry code: (iii) x - 1, y, z] (Table 1 ▸), forming chain structures along the a-axis direction (Fig. 2 ▸). In addition, the host mol­ecules linked by another C—H⋯π inter­action [C12⋯H12⋯Cg1ⁱ; H12⋯Cg1ⁱ = 2.93 Å; C12⋯Cg1 = 3.8374 (15) Å; Cg1 is the centroid of the C36–C41 ring; symmetry code: (i) x,  − y, z − ] (Table 1 ▸), forming a ribbon structure along the c-axis direction (Fig. 3 ▸). As a result, the mol­ecules are cross-linked via C—H⋯π inter­actions into a three-dimensional network.

4. Database survey

A search of the Cambridge Structural Database (CSD, Version 2024.1.0, update of March 2024; Groom et al., 2016 ▸) using ConQuest (Bruno et al., 2002 ▸) for compounds containing carbazole skeleton gave 6572 hits, and for those containing two 3,9-di­methyl­enecarbazole fragments gave 573 hits. Among those, the [3.3](3,9)-CZP skeleton gave four hits. Of these four compounds, three structures are PO-carbazolophanes with the same skeleton as the title compound, [3.3](3,9)-N-sulfonamide-bridged PO-CZP (YUKYEL; Tani et al., 2020 ▸), [3.3](3,9)-N-cyanamide-bridged PO-CZP (BACKOG; Tani et al., 2001 ▸), and [3.3](3,9)-N-n-butyl­amine-bridged PO-CZP (XEBDAN; Kubono et al., 2022 ▸). One structure is [3.3](3,9)-N-cyanamide-bridged fully overlapped (FO)-CZP, syn-3-cyano-3-aza-1(9,3),3(3,9)-dicarbazola­cyclo­octa­phane benzene clathrate (BACKIA; Tani et al., 2001 ▸). In addition to these, we have recently reported the structures of newly chiral [3.3](3,9)-N-(R)-phenethyl­amine-bridged (S_p)-PO-CZP (YOLRAW; Tani et al., 2023 ▸).

5. Synthesis and crystallization

A solution of 9,9′-(1,3-propanedi­yl)bis­[3-(bromo­meth­yl)-9H-carbazole] (370 mg, 0.66 mmol; Tani et al., 2001 ▸) in di­chloro­methane (200 mL) was added to a 500 mL flask, which contained a mixture of tetra­butyl­ammonium iodide (85.0 mg, 0.23 mmol) and 4-cyano­aniline (82 mg, 0.69 mmol) in di­chloro­methane ­(150 mL) and sodium hydroxide (1.16 g, 29 mmol) in water (10 mL). Then, the flask was filled with argon and was stirred at room temperature for 3 d. The reaction mixture was washed with water, then the organic layer was washed with sat. aq. NaCl, and dried over anhydrous sodium sulfate. The solvent was removed under reduced pressure, and the residue was purified by silica gel chromatography (Wako-gel C-200, 10 g). Elution from benzene gave a white solid (21.2 mg, 0.041 mmol, 6%). It was recrystallized from di­chloro­methane:ethanol (1:3) to give a colourless crystal of the title compound suitable for X-ray diffraction. Melting point (decomposition): 561–563 K. ¹H NMR (CDCl₃, 400 MHz): δ = 2.88–2.97 (m, 2H), 3.71–3.81 (m, 2H), 4.12–4.20 (m, 2H), 4.79, 4.99 (ABq, J = 15.6 Hz, 4H), 5.35 (d, J = 8.4 Hz, 2H), 6.19 (d, J = 8.8 Hz, 2H), 7.23–7.33 (m, 4H), 7.48–7.55 (m, 4H), 7.62 (d, J = 8.4 Hz, 2H), 7.74 (s, 2H), 8.08 (d, J = 7.2 Hz, 2H).

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.
