Abstract
In the title compound, C27H29BrN2, the carbazole ring system is essentially planar, with an r.m.s. deviation of 0.0781 (16) Å. An intramolecular N—H⋯N hydrogen bond forms an S(6) ring motif. One of the tert-butyl substituents shows rotational disorder over two sites with occupancies of 0.592 (3) and 0.408 (3). In the crystal, two molecules are associated into an inversion dimer through a pair of C—H⋯π interactions. The dimers are further linked by another pair of C—H⋯π interactions, forming a ribbon along the c-axis direction. A C—H⋯π interaction involving the minor disordered component and the carbazole ring system links the ribbons, generating a network sheet parallel to (100).
Chemical context
Carbazole derivatives have been widely applied in various fields such as pharmaceuticals (Obora, 2018 ▸), electroluminescent materials (Krucaite & Grigalevicius, 2019 ▸; Taneda, et al., 2015 ▸) and dyes (Zhao et al., 2019 ▸). As a result of the high acidity of the N—H bond, 9H-carbazoles have also attracted much attention as hydrogen donors in hydrogen-bonding systems (Rubio et al., 2015 ▸; Wiosna-Sałyga et al., 2006 ▸). Substitution of the 1 position of 9H-carbazole with a hydrogen acceptor can afford an intramolecular hydrogen-bonding system in the molecules. In this work, a Schiff base including carbazole, N-(3,6-di-tert-butyl-9H-calbazol-1-ylmethylidene)-4-bromoaniline, is newly synthesized. 3,6-Di-tert-butyl-9H-carbazole is useful in order to substitute the 1-position of the 9H-carbazole moiety because the substitution reaction would only occur at its 1- and 8-positions. Thus, the title compound has two tert-butyl groups on the carbazole moiety. The title compound is a suitable model to investigate an intramolecular hydrogen bond between the heteroaromatic N—H and the N atom of the imino group. We report herein on its molecular and crystal structures.
Structural commentary
The molecular structure of the title compound is shown in Fig. 1 ▸. The molecule adopts an E configuration with respect to the C=N double bond. The carbazole ring is almost planar with a maximum deviation of 0.0781 (16) Å at atom C8. There is an intramolecular N—H⋯N hydrogen bond involving the amino group (N3—H3) in the carbazole ring and an imine N atom (N2), generating an S(6) ring motif (Table 1 ▸). The dihedral angle between the mean planes of the carbazole ring system and the benzene C25–C30 ring is 42.72 (7)°. The bond lengths and angles of the title compound are normal and agree with those values in other carbazole imine compounds (Gibson et al., 2003 ▸; Nolla-Saltiel et al., 2018 ▸). One of the tert-butyl substituents shows rotational disorder around the C13—C20 bond axis over two sites with occupancies of 0.592 (3) and 0.408 (3).

Supramolecular features
In the crystal, two molecules are associated through a pair of C—H⋯π interactions (C22A—H22C⋯Cg1i in the major disorder component or C21B—H21E⋯Cg1i in the minor disorder component; Cg1 is the centroid of the C25–C30 ring; symmetry code as in Table 1 ▸), forming a centrosymmetric dimer. The dimers are linked by another pair of C—H⋯π interactions (C29—H29⋯Cg2ii; Cg2 is the centroid of the C4–C9 ring; symmetry code as in Table 1 ▸), forming a ribbon along the c-axis direction (Fig. 2 ▸). These ribbons are linked via a C—H⋯π interaction involving the minor disorder component (C22B—H22D⋯Cg3iii; Cg3 is the centroid of the N3/C4/C5/C11/C10 ring; symmetry code as in Table 1 ▸) into a network sheet parallel to (100) (Fig. 3 ▸).

Database survey
A search of the Cambridge Structural Database (CSD, Version 5.40; February 2019; Groom et al., 2016 ▸) gave 56 and 5 hits, respectively, for the 3,6-di-tert-butyl-9H-carbazole and 9H-carbazol-1-ylmethylidene fragments. Of these structures, the compounds that resemble the title compound are (3,6-di-tert-butyl-9H-carbazole-1,8-diyl)bis[N-(naphthalen-1-yl)methanimine] (Nolla-Saltiel et al., 2018 ▸) and 1,8-bis[(2,4,6-trimethylphenyl)iminomethyl]-3,6-dimethyl-9H-carbazole (Gibson et al., 2003 ▸).
Synthesis and crystallization
3,6-Di-tert-butyl-9H-carbazole-1-carbaldehyde (154 mg, 0.50 mmol) and 4-bromoaniline (86 mg, 0.50 mmol) were treated in xylene (10 ml) at 423 K under inert gas overnight, followed by evaporation. The recrystallization of the residue from a solvent mixture of acetone and methanol (1:1, v:v) afforded single crystals of the title compound suitable for X-ray structure analysis (97 mg, 0.21 mmol; yield 42%). 1H NMR (CDCl3, 400 MHz) δ = 1.47 [s, 9H, C(CH3)3], 1.49 [s, 9H, C(CH3)3], 7.22 (td, 2H, Jortho = 8.6 Hz, Jmeta = 2.4 Hz, ArH), 7.47–7.58 (m, 4H, ArH), 7.67 (d, 1H, Jmeta = 1.8 Hz, ArH), 8.13 (d, 1H, Jmeta = 1.8 Hz, ArH), 8.26 (d, 1H, Jmeta = 1.7 Hz, ArH), 8.72 (s, 1H, CH=N), 10.55 (b, 1H, NH). HR–MS (m/z): calculated for [C27H30BrN2]+, m/z = 461.1587; found, 461.1627.
Refinement
Crystal data, data collection and structure refinement details are summarized in Table 2 ▸. The H atom attached to atom N3 was located in a difference-Fourier map and freely refined. The C-bound H atoms were positioned geometrically (C—H = 0.93–0.96 Å) and refined using a riding model with U iso(H) = 1.2U eq(C). Orientational disorder of the tert-butyl substituent (C20–C23) around the C13—C20 bond axis is observed and the occupancies refined to 0.592 (3) and 0.408 (3).

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. |
| Refinement. Refinement was performed using all reflections. The weighted R-factor (wR) and goodness of fit (S) are based on F2. R-factor (gt) are based on F. The threshold expression of F2 > 2.0 sigma(F2) is used only for calculating R-factor (gt). |
