Abstract

The title compound, C₂₄H₂₇Cl₂NOS, contains 1,4-benzo­thia­zine and 2,4-di­chloro­phenyl­methyl­idene units in which the di­hydro­thia­zine ring adopts a screw-boat conformation. In the crystal, inter­molecular C—H_Bnz⋯O_Thz (Bnz = benzene and Thz = thia­zine) hydrogen bonds form chains of mol­ecules extending along the a-axis direction, which are connected to their inversion-related counterparts by C—H_Bnz⋯Cl_Dchlphy (Dchlphy = 2,4-di­chloro­phen­yl) hydrogen bonds and C—H_Dchlphy⋯π (ring) inter­actions. These double chains are further linked by C—H_Dchlphy⋯O_Thz hydrogen bonds, forming stepped layers approximately parallel to (012). The Hirshfeld surface analysis of the crystal structure indicates that the most important contributions for the crystal packing are from H⋯H (44.7%), C⋯H/H⋯C (23.7%), Cl⋯H/H⋯Cl (18.9%), O⋯H/H⋯O (5.0%) and S⋯H/H⋯S (4.8%) inter­actions. Hydrogen-bonding and van der Waals inter­actions are the dominant inter­actions in the crystal packing. Computational chemistry indicates that in the crystal, C—H_Dchlphy⋯O_Thz, C—H_Bnz⋯O_Thz and C—H_Bnz⋯Cl_Dchlphy hydrogen-bond energies are 134.3, 71.2 and 34.4 kJ mol⁻¹, respectively. Density functional theory (DFT) optimized structures at the B3LYP/6–311 G(d,p) level are compared with the experimentally determined mol­ecular structure in the solid state. The HOMO–LUMO behaviour was elucidated to determine the energy gap. The two carbon atoms at the end of the nonyl chain are disordered in a 0.562 (4)/0.438 (4) ratio.

Chemical context  

A number of sulfur- and nitro­gen-containing heterocyclic compounds have been well studied. These mol­ecules exhibit a wide range of biological applications, indicating that the 1,4-benzo­thia­zine moiety is a potentially useful template in medicinal chemistry research with therapeutic applications in the anti­microbial (Armenise et al., 2012 ▸, Sabatini et al., 2008 ▸), anti-viral (Malagu et al., 1998 ▸), anti-oxidant (Zia-ur-Rehman et al. 2009 ▸), anti-inflammatory (Trapani et al., 1985 ▸; Gowda et al., 2011 ▸) anti­pyretic (Warren et al., 1987 ▸), and anti-cancer (Gupta et al., 1991 ▸; Gupta et al., 1985 ▸) areas as well as being precursors for the synthesis of new compounds (Sebbar et al., 2015a ▸; Vidal et al., 2006 ▸) possessing anti-diabetic (Tawada et al., 1990 ▸) and anti-corrosion activities (Ellouz et al., 2016a ▸,b ▸; Sebbar et al., 2016a ▸) and biological properties (Hni et al., 2019a ▸; Ellouz et al., 2017a ▸,b ▸, 2018 ▸; Sebbar et al., 2019a ▸,b ▸). As a continuation of our research into the development of new 1,4-benzo­thia­zine derivatives with potential pharmacological applications, we have studied the reaction of 1-bromo­nonane with (Z)-2-(2,4-di­chloro­benzyl­idene)-2H-1,4-benzo­thia­zin-3(4H)-one under phase-transfer catalysis conditions using tetra-n-butyl­ammonium bromide (TBAB) as catalyst and potassium carbonate as base (Hni et al., 2019b ▸; Sebbar et al., 2019) to give the title compound, (I), in good yield. We report here its crystalline and mol­ecular structures as well as the Hirshfeld surface analysis and the density functional theory (DFT) computational calculations.

Structural commentary  

The title compound contains 1,4-benzo­thia­zine and 2,4-di­chloro­phenyl­methyl­idene units (Fig. 1 ▸), in which the di­hydro­thia­zine ring, B (S1/N1/C1/C6–C8), adopts a screw-boat conformation with puckering parameters Q _T = 0.5581 (16) Å, θ = 69.76 (18)° and φ = 334.3 (2)°. The planar rings, A (C1–C6) and C (C10–C15) are oriented at a dihedral angle of 88.45 (7)°. Atoms Cl1, Cl2 and C9 are almost co-planar with ring C being displaced by 0.0247 (6), −0.0732 (9) and −0.0274 (2) Å, respectively.

Supra­molecular features  

In the crystal, C—H_Bnz⋯O_Thz (Bnz = benzene and Thz = thia­zine) hydrogen bonds link the mol­ecules, forming chains extending along the a-axis direction, which are connected to their inversion-related counterparts by C—H_Bnz⋯Cl_Dchlphy (Dchlphy = 2,4-di­chloro­phen­yl) hydrogen bonds and C—H_Dchlphy⋯π (ring) inter­actions (Table 1 ▸ and Fig. 2 ▸). These double chains are further linked by C—H_Dchlphy⋯O_Thz hydrogen bonds to form stepped layers approximately parallel to (012) (Table 1 ▸ and Figs. 2 ▸ and 3 ▸).

Hirshfeld surface analysis  

In order to visualize the inter­molecular inter­actions in the crystal of the title compound, a Hirshfeld surface (HS) analysis (Hirshfeld, 1977 ▸; Spackman & Jayatilaka, 2009 ▸) was carried out by using Crystal Explorer 17.5 (Turner et al., 2017 ▸). In the HS plotted over d _norm (Fig. 4 ▸), the white surface indicates contacts with distances equal to the sum of van der Waals radii, and the red and blue colours indicate distances shorter (in close contact) or longer (distinct contact) than the van der Waals radii (Venkatesan et al., 2016 ▸). The bright-red spots appearing near O1 and hydrogen atom H15 indicate their roles as the respective donors and/or acceptors; they also appear as blue and red regions corresponding to positive and negative potentials on the HS mapped over electrostatic potential (Spackman et al., 2008 ▸; Jayatilaka et al., 2005 ▸) as shown in Fig. 5 ▸. The blue regions indicate positive electrostatic potential (hydrogen-bond donors), while the red regions indicate negative electrostatic potential (hydrogen-bond acceptors). The shape-index of the HS is a tool to visualize π–π stacking by the presence of adjacent red and blue triangles; if there are no adjacent red and/or blue triangles, then there are no π–π inter­actions. Fig. 6 ▸ clearly suggests that there are no π–π inter­actions in (I). The overall two-dimensional fingerprint plot, Fig. 7 ▸ a, and those delineated into H⋯H, C⋯H/H⋯C, Cl⋯H/H ⋯ Cl, O⋯H/H⋯O and S⋯H/H⋯S contacts (McKinnon et al., 2007 ▸) are illustrated in Fig. 7 ▸ b–f, respectively, together with their relative contributions to the Hirshfeld surface. The most important inter­action is H⋯H (Table 2 ▸), contributing 44.7% to the overall crystal packing, which is reflected in Fig. 7 ▸ b as widely scattered points of high density due to the large hydrogen content of the mol­ecule with the tip at d _e = d _i = 1.09 Å. The presence of C—H⋯π inter­actions is indicated by the fringed pairs of characteristic wings in the fingerprint plot delineated into C⋯H/H⋯C contacts (Fig. 7 ▸ c, 23.7% contribution to the HS). The two pairs of wings in the fingerprint plot delineated into Cl⋯Hl/H⋯Cl contacts (Fig. 7 ▸ d, 18.9% contribution) have an unsymmetrical distribution of points due to a third wing, with the edges at d _e + d _i = 2.74 Å (for the long wing), d _e + d _i = 2.92 Å (for the short wing) and d _e + d _i = 3.53 Å (for the unsymmetrical third wing). The pair of wings in the fingerprint plot delineated into O⋯H/H⋯O contacts (Fig. 7 ▸ e, 5.0% contribution) has a pair of spikes with the tips at d _e + d _i = 2.22 Å. Finally, the wings in the fingerprint plot delineated into S⋯H/H⋯S contacts (Fig. 7 ▸ f, 4.8% contribution) have the tips at d _e + d _i = 2.99 Å.

The Hirshfeld surface representations with the function d _norm plotted onto the surface are shown for the H⋯H, C⋯H/H⋯C, Cl⋯H/H⋯Cl, O⋯H/H⋯O and S⋯H/H⋯S inter­actions in Fig. 8 ▸ a–e, respectively.

The Hirshfeld surface analysis confirms the importance of H-atom contacts in establishing the packing. The large number of H⋯H, C⋯H/H⋯C, Cl⋯H/H⋯Cl and O⋯H/H⋯O inter­actions suggest that van der Waals inter­actions and hydrogen bonding play the major roles in the crystal packing (Hathwar et al., 2015 ▸).

Inter­action energy calculations  

The inter­molecular inter­action energies were calculated using the CE–B3LYP/6–31G(d,p) energy model available in Crystal Explorer 17.5 (Turner et al., 2017 ▸), where a cluster of mol­ecules is generated by applying crystallographic symmetry operations with respect to a selected central mol­ecule within the default radius of 3.8 Å (Turner et al., 2014 ▸). The total inter­molecular energy (E _tot) is the sum of electrostatic (E _ele), polarization (E _pol), dispersion (E _dis) and exchange-repulsion (E _rep) energies (Turner et al., 2015 ▸) with scale factors of 1.057, 0.740, 0.871 and 0.618, respectively (Mackenzie et al., 2017 ▸). Hydrogen-bonding inter­action energies (in kJ mol⁻¹) were calculated to be −53.7 (E _ele), −13.6 (E _pol), −161.9 (E _dis), 119.0 (E _rep) and −134.3 (E _tot) for C—H_Dchlphy⋯O_Thz, 25.6 (E _ele), −5.7 (E _pol), −62.1 (E _dis), 23.1 (E _rep) and −71.2 (E _tot) [or C—H_Bnz⋯O_Thz and −16.0 (E _ele), −8.3 (E _pol), −43.0 (E _dis), 42.2 (E _rep) and −34.4 (E_{t ot}) for C—H_Bnz⋯Cl_Dchlphy (Bnz = benzene, Thz = thia­zine and Dchlphy = 2,4-di­chloro­phen­yl).

DFT calculations  

The optimized structure of the title compound, (I), in the gas phase was generated theoretically via density functional theory (DFT) using the standard B3LYP functional and 6–311G(d,p) basis-set calculations as implemented in GAUSSIAN 09 (Frisch et al., 2009 ▸). The theoretical and experimental results are in good agreement (Table 3 ▸). The highest-occupied mol­ecular orbital (HOMO), acting as an electron donor, and the lowest-unoccupied mol­ecular orbital (LUMO), acting as an electron acceptor, are very important parameters for quantum chemistry. When the energy gap is small, the mol­ecule is highly polarizable and has high chemical reactivity. The DFT calculations provide some important information on the reactivity and site selectivity of the mol­ecular framework. E _HOMO and E _LUMO clarify the inevitable charge-exchange collaboration inside the studied material, and together with the electronegativity (χ), hardness (η), potential (μ), electrophilicity (ω) and softness (σ) are recorded in Table 4 ▸. The significance of η and σ is to evaluate both the reactivity and stability. The electron transition from the HOMO to the LUMO energy level is shown in Fig. 9 ▸. The HOMO and LUMO are localized in the plane extending from the whole (2Z)-2-[(2,4-di­chloro­phen­yl)methyl­idene]-4-nonyl-3,4-di­hydro-2H-1,4-benzo­thia­zin-3-one ring.

Database survey  

A search in the Cambridge Structural Database (Groom et al., 2016 ▸; updated to October 2019), for compounds containing the fragment II gave 14 hits.

The largest set contains IIa (COGRUN; Sebbar et al., 2014a ▸), IIb (APAJUY; Sebbar et al., 2016c ▸), IIc (EVIYIT; Sebbar et al., 2016b ▸) and IId (WUFGIP; Sebbar et al., 2015b ▸). Additional examples are III: R ₁ = 4-FC₆H₄ and R ₂ = CH₂C≡CH (WOCFUS; Hni et al., 2019a ▸), R ₁ = 4-ClC₆H₄ and R ₂ = CH₂Ph (OMEGEU; Ellouz et al., 2016c ▸) and R ₁ = 2-ClC₆H₄, R ₂ = CH₂C≡CH (SAVTUH; Sebbar et al., 2017 ▸). In all these compounds, the configuration about the benzyl­idene group: C=CHC₆H₅ bond is Z, and in the majority of these, the heterocyclic ring is quite non-planar with the dihedral angle between the plane defined by the benzene ring plus the nitro­gen and sulfur atoms and that defined by nitro­gen and sulfur and the other two carbon atoms separating them having approximate values of 36° (WUFGIP), 29° (APAJUY), 28° (SAVTUH), 26° (WOCFUS) and 25° (COGRUN). By contrast, in both EVIYIT and OMEGEU, the benzo­thia­zine unit is nearly planar with the corresponding dihedral angle being about 4°.

Synthesis and crystallization  

To a solution of (Z)-2-(2,4-di­chloro­benzyl­idene)-2H-1,4-benzo­thia­zin-3(4H)-one (1.5 mmol), potassium carbonate (2.7 mmol) and tetra-n-butyl ammonium bromide (0.14 mmol) in DMF (20 mL) was added 1-bromo­nonane (2.6 mmol). Stirring was continued at room temperature for 24 h. The mixture was filtered and the solvent removed. The residue obtained was washed with water. The organic compound was chromatographed on a column of silica gel with ethyl acetate–hexane (9/1) as eluent. Colourless crystals were isolated when the solvent was allowed to evaporate (yield = 79%).

Refinement  

Crystal data, data collection and structure refinement details are summarized in Table 5 ▸. The two carbon atoms at the end of the nonyl chain, C23 and C24, are disordered in a 0.562 (4)/0.438 (4) ratio. These were refined with restraints that the two components have comparable geometries. The H atoms on these carbons as well as those on C22 were included as riding contributions in idealized positions (C—H = 0.99 Å with U _iso(H) = 1.5U _eq(C).

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. The two carbons at the end of the nonyl chain, C23 and C24, are disordered in a 0.562 (4)/0.438 (4) ratio. These were refined with restraints that the two components have comparable geometries. The H-atoms on these carbons as well as those on C22 were included as riding contributions in idealized positions.
