Crystal structures of 4-meth­oxy-N-(4-methyl­phenyl)benzene­sulfonamide and N-(4-fluoro­phenyl)-4-meth­oxy­benzene­sulfonamide

In the crystal structures of 4-meth­oxy-N-(4-methyl­phen­yl)benzene­sulfonamide and N-(4-fluoro­phen­yl)-4-meth­oxy­benzene­sulfonamide, the supra­molecular architecture of the former is controlled by C—H⋯π_ar­yl inter­actions, forming a two-dimensional architecture, while in the latter, a pair of C—H⋯O inter­molecular inter­actions lead to the formation of a three-dimensional architecture.

Abstract

Crystal structures of two N-(ar­yl)aryl­sulfonamides, namely, 4-meth­oxy-N-(4-methyl­phen­yl)benzene­sulfonamide, C₁₄H₁₅NO₃S, (I), and N-(4-fluoro­phen­yl)-4-meth­oxy­benzene­sulfonamide, C₁₃H₁₂FNO₃S, (II), were determined and analyzed. In (I), the benzene­sulfonamide ring is disordered over two orientations, in a 0.516 (7):0.484 (7) ratio, which are inclined to each other at 28.0 (1)°. In (I), the major component of the sulfonyl benzene ring and the aniline ring form a dihedral angle of 63.36 (19)°, while in (II), the planes of the two benzene rings form a dihedral angle of 44.26 (13)°. In the crystal structure of (I), N—H⋯O hydrogen bonds form infinite C(4) chains extended in [010], and inter­molecular C—H⋯π_ar­yl inter­actions link these chains into layers parallel to the ab plane. The crystal structure of (II) features N—H⋯O hydrogen bonds forming infinite one dimensional C(4) chains along [001]. Further, a pair of C—H⋯O inter­molecular inter­actions consolidate the crystal packing of (II) into a three-dimensional supra­molecular architecture.

Chemical context  

Sulfonamide drugs were the first among the chemotherapeutic agents to be used for curing and preventing bacterial infection in human beings (Shiva Prasad et al., 2011 ▸). They play a vital role as a key constituent in a number of biologically active mol­ecules. Up to now, sulfonamides have been known to exhibit a wide variety of biological activities, such as anti­bacterial (Subhakara Reddy et al., 2012 ▸; Himel et al., 1971 ▸), anti­fungal (Hanafy et al., 2007 ▸), anti­inflamatory (Kuçukguzel et al., 2013 ▸), anti­tumor (Ghorab et al., 2011 ▸), anti­cancer (Mansour et al., 2011 ▸), anti-HIV (Sahu et al., 2007 ▸) and anti­tubercular activities (Vora & Mehta, 2012 ▸). In recent years, extensive research studies have been carried out on the synthesis and evaluation of pharmacological activities of mol­ecules containing the sulfonamide moiety for different activities, and have been reported to be important pharmacophores (Mohan et al., 2013 ▸).

With these considerations in mind and based on our structural study of N-(4-substituted-phen­yl)-4-meth­oxy­benzene­sulfonamides (Vinola et al., 2015 ▸), we report herein the crystal structures of 4-meth­oxy-N-(4-methyl­phen­yl)benzene­sulfonamide, (I), and N-(4-fluoro­phen­yl)-4-meth­oxy­benzene­sulfonamide, (II).

Structural commentary  

In (I) (Fig. 1 ▸), the benzene­sulfonamide ring is disordered due to rotation across the C_ar—S(O₂) bond over two orientations, with atoms C2, C3, C5 and C6 occupying two positions with a 0.516 (7):0.484 (7) ratio. The dihedral angle between the two parts of disordered benzene ring, i.e. C1/C2A/C3A/C4/C5A/C6A and C1/C2B/C3B/C4/C5B/C6B, is 28.0 (1)°. The dihedral angle between the sulfonyl benzene ring (considering the major component) and the aniline ring is 63.36 (19)°, and the N—C bond in the C—SO₂—NH—C segment has a gauche torsion with respect to the S=O bonds. Further, the mol­ecule is twisted at the S—N bond, with a C1—S1—N1—C7 torsion angle of 66.33 (19)°. The meth­oxy group in the sulfonyl­benzene ring is in the same plane as that of the major component of the disordered sulfonyl­benzene ring, the torsion angle C5A—C4—O3—C14 being −176.2 (4)°, while it deviates slightly from planarity with respect to the minor component, the C5B—C4—O3—C14 torsion angle being 165.9 (4)°.

In (II) (Fig. 2 ▸), the dihedral angle between the two benzene rings of 44.26 (13)° is less than that observed in (I), and the N—C bond in the C—SO₂—NH—C segment has a gauche torsion with respect to the S=O bonds. Further, the mol­ecule is twisted at the S—N bond, with a C1—S1—N1—C7 torsion angle of 68.4 (2)°. Similar to (I), the meth­oxy group in the sulfonyl­benzene ring is in the same plane as that of the sulfonyl­benzene ring, the C5—C4—O3—C13 torsion angle being 177.0 (2)°.

Supra­molecular features  

In the crystal structure of (I), N1—H1⋯O2 hydrogen bonds (Table 1 ▸) link the mol­ecules into infinite one-dimensional C(4) chains along [010]. Neighbouring C(4) chains are inter­connected via C—H⋯π_ar­yl inter­actions (Table 1 ▸) into layers (Fig. 3 ▸) parallel to the ab plane.

The crystal structure of (II) features N1—H1⋯O2 hydrogen bonds (Fig. 4 ▸ and Table 2 ▸), forming infinite one-dimensional C(4) chains along [001]. Further, weak inter­molecular C—H⋯O inter­actions (Table 2 ▸) consolidate the crystal packing of (II), leading to a three-dimensional supra­molecular architecture (Fig. 5 ▸).

Database survey  

Three N-(4-substituted-phen­yl)-4-meth­oxy­benzene­sul­fon­am­ides (Vinola et al., 2015 ▸), namely, 4-meth­oxy-N-(phen­yl)benzene­sulfonamide, (III), 4-meth­oxy-N-(4-meth­oxy­phen­yl)benzene­sulfonamide, (IV), and N-(4-chloro­phen­yl)-4-meth­oxy­benzene­sulfonamide, (V), have been reported previously. Compounds (IV) and (V) crystallize in monoclinic syngony, while compound (III) crystallizes in ortho­rhom­bic syngony. The dihedral angles between the two benzene rings in (III), (IV) and (V) are 55.1 (1), 56.3 (1) and 42.6 (1)°, respectively. Comparison of the dihedral angles between the two benzene rings in (I)–(V) shows that, when an electron-donating substituent is introduced into the para position of the aniline ring of (I) it results in a slight increase in the dihedral angle, whereas, when an electron-withdrawing substituent is introduced it decreases the dihedral angle. Further, the mol­ecules of (III), (IV) and (V) are twisted at the S—N bond, with C1—S1—N1—C7 torsion angles of −72.9 (1), 66.2 (1) and 72.5 (1)°, respectively. These values are similar to those observed in (I) and (II).

Comparison of the crystal structures (I) and (V) shows that the effect of introducing an electron-donating substituent into the para position of the aniline ring of (I) is quite different than that due to electron-withdrawing substituents. The crystal structure of (III) features N—H⋯O hydrogen bonds that form C(4) chains, and thus, the supra­molecular architecture is one-dimensional. In (IV), one N—H⋯O hydrogen bond and two alternating C—H⋯π_ar­yl (centroid of aniline ring) inter­actions direct a two-dimensional architecture. This is quite similar to the crystal structure of (I). Thus, the methyl and meth­oxy groups on the aniline ring have similar influence on the crystal structures of these compounds. However, the crystal structures of (II) and (V) are very different. The crystal structure of (V) features N—H⋯O hydrogen bonds that form C(4) chains. Further, (V) does not feature any structuredirecting inter­molecular inter­actions, and thus, the structure is one-dimensional. In contrast to this, the crystal structure of (II) features an N—H⋯O and two C—H⋯O inter­actions, leading to a three-dimensional architecture. Thus, the Cl and F atoms on the aniline ring have very different influences on the crystal structures of these compounds.

Synthesis and crystallization  

Compounds (I) and (II) were prepared according to the literature method of Vinola et al. (2015 ▸). The purity of the compounds were checked by determining the melting points. Single crystals used for X-ray diffraction studies were obtained by slow evaporation of ethanol solutions of the compounds at room temperature.

Refinement  

Crystal data, data collection and structure refinement details are summarized in Table 3 ▸. The amino H atoms were located in a difference map and were refined isotropically with the bond-length restraint N—H = 0.90 (1) Å. To improve considerably the values of R1, wR2, and S (goodness-of-fit), a partially obscured reflection (i.e. 100) was omitted from the final refinement of (I). The two parts (A and B) of the disordered benzene­sulfonyl ring in (I) were restrained to be planar (FLAT instruction), and thus, the r.m.s. deviations (considering non-H atoms) observed for the planes defining the two rings are 0.047 (1) (major-component ring A) and 0.054 (1) Å (minor-component ring B). The disordered atoms (C2, C3, C5 and C6) in both components were isotropically refined, and the C—C bond lengths were restrained to 1.391 (1) Å.

Geometry. All s.u.'s (except the s.u. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell s.u.'s are taken into account individually in the estimation of s.u.'s in distances, angles and torsion angles; correlations between s.u.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell s.u.'s is used for estimating s.u.'s 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 > 2σ(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.

(II) N-(4-Fluorophenyl)-4-methoxybenzenesulfonamide . Special details

Geometry. All s.u.'s (except the s.u. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell s.u.'s are taken into account individually in the estimation of s.u.'s in distances, angles and torsion angles; correlations between s.u.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell s.u.'s is used for estimating s.u.'s 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 > 2σ(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.
