Abstract

In the title compound, C16H13Cl2N3O3S2, the thio-phene ring is disordered in a 0.762 (3):0.238 (3) ratio by an approximate 180° rotation of the ring around the S-C bond linking the ring to the sulfonyl unit. The di-chloro-benzene group is also disordered over two sets of sites with the same occupancy ratio. The mol-ecular conformation is stabilized by intra-molecular C-H⋯Cl and C-H⋯N hydrogen bonds, forming rings with graph-set notation S(5). In the crystal, pairs of mol-ecules are linked by N-H⋯O and C-H⋯O hydrogen bonds, forming inversion dimers with graph-set notation R22(8) and R12(11), which are connected by C-H⋯O hydrogen-bonding inter-actions into ribbons parallel to (100). The ribbons are further connected into a three-dimensional network by C-H⋯π inter-actions and π-π stacking inter-actions between benzene and thio-phene rings, with centroid-to-centroid distances of 3.865 (2), 3.867 (7) and 3.853 (2) Å. Hirshfeld surface analysis has been used to confirm and qu-antify the supra-molecular inter-actions.

Chemical context

The pyrazole core structure has been widely used as a common heterocyclic scaffold in medicinal chemistry to produce novel drug candidates with a great variety of pharmacological activities including anti-inflammatory, anti­platelet, anti­cancer, anti­mycobacterial, anti­depressant and anti­convulsant properties (Küçükgüzel & Şenkardeş, 2015 ▸; Çalışkan et al., 2013 ▸; Ding et al., 2009 ▸; Baraldi et al., 2004 ▸; Palaska et al., 2008 ▸). Among them, pyrazole-carboxamide derivatives have been shown to exhibit anti­mycobacterial, anti­fungal and anti­viral activities (Sun & Zhou, 2015 ▸; Yan et al., 2018 ▸; Comber et al., 1992 ▸). In the course of our ongoing research into bioactive pyrazole derivatives (Banoğlu et al., 2005 ▸; Şüküroğlu et al., 2005 ▸; Ergün et al., 2010 ▸; Çalışkan et al., 2011 ▸; Levent et al., 2013 ▸; Cankara Pirol et al., 2014 ▸), we have relied on the aforementioned biological properties of pyrazole-carboxamides and designed novel pyrazole-3-carboxamide derivatives for their potential anti­microbial activity. In this work, we report the crystallographic characterization and Hirshfeld surface analysis of one of these compounds bearing the 2,4-di­chloro­benzyl substituent at one of the pyrazole nitro­gen atoms.

Structural commentary

Supra­molecular features

In the crystal, pairs of mol­ecules are linked by inter­molecular N—H⋯O and C—H⋯O hydrogen bonds (Table 1 ▸; Figs. 2 ▸ and 3 ▸), forming inversion dimers with graph-set notation (8) and (11), which are connected by C—H⋯O hydrogen-bonding inter­actions into ribbons parallel to (100). The ribbons are further connected into a three-dimensional network by C—H⋯π inter­actions (Table 1 ▸) and π–π stacking inter­actions between the benzene and thio­phene rings, with centroid-to-centroid distances of 3.865 (2) Å for Cg1⋯Cg1v, 3.867 (7) Å for Cg2⋯Cg2v and 3.853 (2) Å for Cg4⋯Cg4vi where Cg1, Cg2 and Cg4 are the centroids of the thio­phene ring B, the thio­phene ring B′ and the benzene ring C [symmetry codes: (v) 2 − x, 1 − y, 1 − z; (vi) 1 − x, 1 − y, −z].

Hirshfeld surface analysis

A Hirshfeld surface analysis (Hirshfeld, 1977 ▸; Spackman & Jayatilaka, 2009 ▸) of the title compound was carried out to investigate the location of atoms with potential to form hydrogen bonds and the qu­anti­tative ratio of these inter­actions. CrystalExplorer17.5 (Turner et al., 2017 ▸) was used to generate the Hirshfeld surface and two-dimensional fingerprint plots (Parkin et al., 2007 ▸; Rohl et al., 2008 ▸), using the atomic coordinates of the major disorder component of the disordered atoms (Figs. 4 ▸ and 5 ▸). The electrostatic potentials were calculated using TONTO (Spackman et al., 2009 ▸) integrated into CrystalExplorer, wherein the respective experimental structure was used as the input to TONTO. Further, the electrostatic potentials were mapped on Hirshfeld surfaces using the STO-3G basis set at the Hartree–Fock level of theory.

The two-dimensional fingerprint plots of the title compound, showing (a) all inter­actions, and delineated into (b) H⋯H, (c) C⋯H, (d) Cl⋯H, (e) Cl⋯Cl and (f) C⋯C inter­actions. The outline of the full fingerprint plots is shown in grey. d i is the closest inter­nal distance from a given point on the Hirshfeld surface and d e is the closest external contact.

The inter­molecular distance information on the surface can be condensed into a two-dimensional histogram of d e and d i, which is a unique identifier for mol­ecules in a crystal structure, and is known as a fingerprint plot. Instead of plotting d e and d i on the Hirshfeld surface, contact distances are normalized in CrystalExplorer using the van der Waals radius of the appropriate inter­nal (r i vdw) and external (r e vdw) atom of the surface: d norm= (d i − r i vdw)/r i vdw + (d e − r e vdw)/r vdw. The mol­ecular Hirshfeld surfaces were obtained using a standard (high) surface resolution with the three-dimentional d norm surfaces mapped over a fixed colour scale of −1.9033 (red) to 1.1934 (blue). In the fingerprint plots (Rohl et al., 2008 ▸), shown in Fig. 5 ▸, the points indicated by b, c, d and e correspond to H⋯H, C⋯H, Cl⋯H, Cl⋯Cl and CC inter­actions with relative contributions of 28.4, 7.0, 6.8, 6.5 and 5.7%, respectively. These types of inter­actions add up to 54.4% of the inter­molecular contacts of the Hirshfeld surface area. The remaining contributions (8.3%) correspond to C⋯Cl (1.3%), N⋯C (1.3%) and other less important inter­actions (<1%). CC contacts correspond to inter­molecular π–π inter­actions. The occurrence of non-high inter­action rates can be attributed to the fact that the small disordered portion of the mol­ecule is not considered.

Database survey

All bond lengths and angles are within normal ranges and are similar to those reported for related mol­ecules such as trans-rac-[1-oxo-2-phenethyl-3-(2-thien­yl)-1,2,3,4-tetra­hydro­iso­quin­olin-4-yl]methyl 4-methyl­benzene­sulfonate (Akkurt et al., 2008 ▸), 2-benzene­sulfonamido­benzoic acid (Asiri et al., 2009 ▸), propyl 2-(4-methyl­benzene­sulfonamido)­benzoate (Mustafa, Khan et al., 2012 ▸), 2-{4-[acet­yl(eth­yl)amino]­benzene­sulfon­am­ido}­benzoic acid (Mustafa, Muhmood et al., 2012 ▸), 2-(5-bromo­pyridin-3-yl)-5-[3-(4,5,6,7-tetra­hydro­thieno[3,2-c]pyridine-5-ylsulfon­yl)thio­phen-2-yl]-1,3,4-oxa­diazole (Fun et al., 2011a ▸) and 2-(biphenyl-4-yl)-5-[3-(4,5,6,7-tetra­hydro­thieno[3,2-c]pyridine-5-ylsulfon­yl) thio­phen-2-yl]-1,3,4-oxa­diazole (Fun et al., 2011b ▸).

Synthesis and crystallization

To a solution of methyl 1-(2,4-di­chloro­benz­yl)-5-methyl-1H-pyrazole-3-carboxyl­ate (200 mg, 0.70 mmol, 1 equiv.) in di­chloro­methane (DCM) were added 2-thio­phene­sulfonamide (126 mg, 0. 77 mmol, 1.1 equiv.), 1-ethyl-3-(3-di­methyl­amino-prop­yl)carbodi­imide (EDC; 148 mg, 0.77 mmol, 1.1 equiv.) and 4-dimethyl-amino­pyridine (DMAP; 17.8 mg, 0.14 mmol, 0.2 equiv.), and the resulting mixture was stirred overnight at room temperature. Upon completion of the reaction, the reaction mixture was partitioned between DCM and water. The collected organic layer was dried over anhydrous Na2SO4, filtered and evaporated to give the crude compound, which was purified with automated-flash chromatography (120.6 mg, 39.95%). The obtained product was recrystallized from hexane and ethyl acetate (4:1), m.p. 464.8–465.3 K. 1H NMR (CDCl3): δ 2.24 (3H, s), 5.33 (2H, s), 6.64 (2H, m), 7.12 (1H, m), 7.21 (1H, dd, J = 8.4, 2.1 Hz), 7.45 (1H, d, J = 2.1 Hz), 7.69 (1H, dd, J = 5.1, 1.2 Hz), 7.97 (1H, dd, J = 3.9, 1.2 Hz), 9.29 (1H, bs); 13C NMR (CDCl3): 11.2, 50.5, 107.6, 127.3, 127.9, 129.1, 129.6, 131.7, 132.9, 133.8, 134.8, 135.1, 139.2, 142.0, 143.5, 158.4. HRMS m/z calculated for C16H13Cl2N3O3S2 [M + H]+ 429.9854; found: 429.9857.

Refinement details

Crystal data, data collection and structure refinement details are summarized in Table 2 ▸. All H atoms bound to carbon atoms were positioned geometrically and treated as riding with C—H = 0.93-0.97 Å and U iso(H) = 1.2U eq(C) or 1.5U eq(C) for methyl H atoms. A rotating model was used for the methyl group. The nitro­gen-bound H atom (H1N) was located in a difference-Fourier map and refined with the constraint N1—H1N = 0.84 (3) Å and U iso(H) = 1.2U eq(N). The thio­phene ring is rotationally disordered by approximately 180° over two positions, the ratio of refined occupancies being 0.762 (3):0.238 (3). The di­chloro­benzene group of the title compound is also disordered over two sets of sites with the same occupancy ratio. The disordered dicholoro­benzene groups (C: C11–C16 and C′: C11A–C16A) were refined as rigid hexa­gons with bond lengths of 1.39 Å. The displacement ellipsoids for the corresponding carbon atoms in the disordered dicholoro­benzene groups were constrained by using the EADP command. Six outliers (633, 30, 30, 515, 51, 520) were omitted in the final cycles of refinement.

Refinement. Refinement on F2 for ALL reflections except those flagged by the user for potential systematic errors. Weighted R-factors wR and all goodnesses of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The observed criterion of F2 > 2sigma(F2) is used only for calculating -R-factor-obs 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.
