C—H⋯Br inter­actions connect mol­ecules in the crystal, resulting in zigzag C(8) chains along the [100] direction. C—Br⋯π inter­actions connect these chains into parallel layers to (002). van der Waals inter­actions between the layers aid in the cohesion of the crystal packing.

Keywords: crystal structure, non-covalent inter­actions, C—H⋯Br inter­actions, C(8) chains, Hirshfeld surface analysis

Abstract

The mol­ecule of the title compound, C14H8Br3N3O2, consists of three almost planar groups: the central di­bromo­ethenyldiazene fragment and two attached aromatic rings. The mean planes of these rings form dihedral angles with the plane of the central fragment of 26.35 (15) and 72.57 (14)° for bromine- and nitro-substituted rings, respectively. In the crystal, C—H⋯Br inter­actions connect mol­ecules, generating zigzag C(8) chains along the [100] direction. These chains are linked by C—Br⋯π inter­actions into layers parallel to (001). van der Waals inter­actions between the layers aid in the cohesion of the crystal packing. The most substantial contributions to crystal packing, according to a Hirshfeld surface analysis, are from Br⋯H/H⋯Br (20.9%), C⋯H/H⋯C (15.2%), O⋯H/H⋯O (12.6%) and H⋯H (11.7%) contacts.

1. Chemical context

Azo dyes constitute the largest production volume (ca 70%) of the dye industry today, and their relative importance may increase further in the future (Lipskikh et al., 2018 ▸). They play a crucial role in the printing market, the design of functional materials attributed to smart hydrogen bonding, photo-triggered structural switching, self-assembled layers, ionophores, liquid crystals, semiconductors, indicators, spectrophotometric reagents for determination of metal ions, photoluminescent materials, catalysts, anti­microbial agents, optical recording media, spin-coating films, etc (Zollinger, 1994 ▸, 1995 ▸; Gurbanov et al., 2020a ▸,b ▸; Mahmudov et al., 2010 ▸, 2013 ▸). Depending on the attached substituents, the functional properties of azo compounds and their metal complexes can be improved/controlled (Ma et al., 2020 ▸, 2021 ▸). Both E/Z isomerism and azo–hydrazo tautomerism properties of azo dyes are key phenomena in the synthesis and development of new functional materials (Shixaliyev et al., 2018 ▸, 2019 ▸). The attachment of non-covalent bond acceptor or donor centres to the azo dyes can be used as a synthetic strategy for the improvement of the functional properties of their metal complexes (Mahmudov et al., 2020 ▸, 2021 ▸, 2022 ▸). Thus, we have attached bromine atoms and a nitro group together with aryl rings to the –N=N– linkage leading to a new azo compound, (E)-2-(4-bromo­phen­yl)-1-[2,2-di­bromo-1-(4-nitro­phen­yl)ethen­yl]diazene, which can provide inter­molecular halogen and hydrogen bonds as well as π-inter­actions. 1.

2. Structural commentary

The mol­ecule of the title compound (Fig. 1 ▸) consists of three almost planar groups: the central di­bromo­ethenyldiazene fragment [largest deviation from the l.s. plane is 0.039 (3) Å for N2] and two attached aromatic rings. The mean planes of these rings form dihedral angles with the plane of the central fragment of 26.35 (15) and 72.57 (14)° for the bromine- and nitro-substituted rings, respectively. The nitro group is twisted by 8.1 (2)° with respect to the C3–C8 aromatic ring. The C2—N2 bond distance of 1.406 (4) Å indicates π-conjugation between ethene and diazo groups. All other bond lengths and angles in the title compound are similar to those reported for the related azo compounds discussed in the Database survey section.

3. Supra­molecular features and Hirshfeld surface analysis

In the crystal, C—H⋯Br inter­actions connect the mol­ecules, generating zigzag C(8) chains (Bernstein et al., 1995 ▸) along the [100] direction (Table 1 ▸, Figs. 2 ▸ and 3 ▸). These chains are linked by C—Br⋯π inter­actions [C1—Br1⋯Cg1ii; C1—Br1 = 1.864 (3) Å, Br1⋯Cg1ii = 3.5803 (16) Å, C1⋯Cg1ii = 4.722 (3) Å, C1—Br1⋯Cg1ii = 116.77 (9)°; Cg1 is the centroid of the C3–C8 ring; symmetry code (ii): x +  Inline graphic , −y +  Inline graphic , z] into layers parallel to (001) (Fig. 4 ▸). van der Waals inter­actions between the layers help to keep the crystal packing together.

Crystal Explorer 17.5 (Turner et al., 2017 ▸) was used to perform a Hirshfeld surface analysis and to generate the corresponding two-dimensional fingerprint plots, with a standard resolution of the three-dimensional d norm surfaces plotted over a fixed color scale of −0.1401 (red) to 1.1158 (blue) a.u. (Fig. 5 ▸). The red patches represent short contacts and negative d norm values on the surface, which correspond to the C—H⋯Br hydrogen bonds discussed above (Table 1 ▸). The C10—H10⋯Br1 inter­actions, which are important for mol­ecular packing of the title compound, are responsible for the red patch that appears around Br1.

4. Database survey

A search of the Cambridge Structural Database (CSD, Version 5.42, update of September 2021; Groom et al., 2016 ▸) for similar structures with the (E)-1-(2,2-di­bromo-1-phenyl­ethen­yl)-2-phenyl­diazene fragment showed that the nine closest are those of CSD refcodes TAZDIL [(I); Atioğlu et al., 2022 ▸], PAXDOL [(II); Çelikesir et al., 2022 ▸], GUPHIL [(III); Özkaraca et al., 2020b ▸], HONBUK [(IV); Akkurt et al., 2019 ▸], HONBOE [(V); Akkurt et al., 2019 ▸], HODQAV [(VI); Shikhaliyev et al., 2019 ▸], XIZREG [(VII); Atioğlu et al., 2019 ▸], LEQXOX [(VIII); Shikhaliyev et al., 2018 ▸] and LEQXIR [(IX); Shikhaliyev et al., 2018 ▸].

In (I), the mol­ecules are connected by C—H⋯O and C—H⋯F hydrogen bonds into layers parallel to (011). The crystal packing is consolidated by C—Br⋯π and C—F⋯π contacts, as well as by π–π stacking inter­actions. In the crystal of (II), the mol­ecules are linked into chains running parallel to [001] by C—H⋯O hydrogen bonds. The crystal packing is consolidated by C—F⋯π contacts and π–π stacking inter­actions, and short Br⋯O [2.9828 (13) Å] distances are also observed. In the crystal of (III), the mol­ecules are linked into inversion dimers via short halogen–halogen contacts [Cl1⋯Cl1 = 3.3763 (9) Å, C16—Cl1⋯Cl1 = 141.47 (7)°] compared to the van der Waals radius sum of 3.50 Å for two chlorine atoms. No other directional contacts could be identified, and the shortest aromatic ring centroid separation is greater than 5.25 Å. In the crystals of (IV) and (V), the mol­ecules are linked through weak X⋯Cl contacts [X = Cl for (IV) and Br for (V)], C—H⋯Cl and C—Cl⋯π inter­actions into sheets lying parallel to (001). In the crystal of (VI), the mol­ecules are stacked in columns parallel to [100] via weak C—H⋯Cl hydrogen bonds and face-to-face π–π stacking inter­actions. The crystal packing is further consolidated by short Cl⋯Cl contacts. In (VII), mol­ecules are linked by C—H⋯O hydrogen bonds into zigzag chains running parallel to [001]. The crystal packing also features C—Cl⋯π, C—F⋯π and N—O⋯π inter­actions. In (VIII), C—H⋯N and short Cl⋯Cl contacts are observed, and in (IX), C—H⋯N and C—H⋯O hydrogen bonds and short Cl⋯O contacts occur.

5. Synthesis and crystallization

This dye was synthesized according to the reported method (Akkurt et al., 2019 ▸; Atioğlu et al., 2019 ▸; Maharramov et al., 2018 ▸; Özkaraca et al., 2020a ▸,b ▸). A 20 mL screw neck vial was charged with DMSO (10 mL), (E)-1-(4-bromo­phen­yl)-2-(4-nitro­benzyl­idene)hydrazine (1 mmol), tetra­methyl­ethylene­di­amine (TMEDA; 295 mg, 2.5 mmol), CuCl (2 mg, 0.02 mmol) and CBr4 (4.5 mmol). After 1-3 h (until TLC analysis showed complete consumption of corresponding Schiff base), the reaction mixture was poured into 0.01 M solution of HCl (100 mL, pH = 2–3), and extracted with di­chloro­methane (3 × 20 mL). The combined organic phase was washed with water (3 × 50 mL), brine (30 mL), dried over anhydrous Na2SO4 and concentrated in vacuo using a rotary evaporator. The residue was purified by column chromatography on silica gel using appropriate mixtures of hexane and di­chloro­methane (3/1–1/1). Crystals suitable for X-ray analysis were obtained by slow evaporation of an ethanol solution. Red solid (58%); m.p. 398 K. Analysis calculated for C14H8Br3N3O2 (M = 489.95): C 34.32, H 1.65, N 8.58; found: C 34.27, H 1.70, N 8.56%. 1H NMR (300 MHz, CDCl3) δ 8.16–7.41 (8H, Ar–H). 13C NMR (75MHz, CDCl3) δ 150.89, 149.62, 148.26, 136.43, 132.25, 127.77, 125.57, 124.53, 123.57, 93.24. ESI–MS: m/z: 490.96 [M + H]+.

6. Refinement

Crystal data, data collection and structure refinement details are summarized in Table 3 ▸. All H atoms were positioned geometrically and constrained to ride on their parent atoms (C—H = 0.95 Å) with U iso(H) = 1.2U eq(C). One reflection (110), affected by the beam stop, was omitted in the final cycles of refinement.

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 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 > 2sigma(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.
