Crystal structure and Hirshfeld surface analysis of (E)-N′-benzyl­idene-4-chloro­benzene­sulfono­hydrazide and of its (E)-4-chloro-N′-(ortho- and para-methyl­benzyl­idene)benzene­sulfono­hydrazide derivatives

The crystal structures of (E)-N′-(benzyl­idene)-4-chloro­benzene­sulfono­hydrazide (I) and its ortho- and para-methyl-substituted benzyl­idene derivatives, (E)-N′-(2-methyl­benzyl­idene)-4-chloro-benzene­sulfono­hydrazide (II) and (E)-N′-(4-methyl­benzyl­idene)-4-chloro­benzene­sulfono­hydrazide (III), have been studied to investigate the effect of substitution on the structural and supra­molecular features of these compounds.

Abstract

(E)-N′-Benzyl­idene-4-chloro­benzene­sulfono­hydrazide, C₁₃H₁₁ClN₂O₂S, (I), and its ortho- and para-methyl­substituted derivatives, C₁₄H₁₃ClN₂O₂S, namely (E)-4-chloro-N′-(2-methyl­benzyl­idene)benzene­sulfono­hydrazide, (II), and (E)-4-chloro-N′-(4-methyl­benzyl­idene)benzene­sulfono­hydrazide, (III), have been synthesized, characterized spectroscopically and their crystal structures determined to investigate the effect of the substitution site of the benzyl­idene group on the structural and supra­molecular features in these compounds. Compounds (I) and (II) are isotypic while compound (III) is different. All three mol­ecules are bent at the S atom with C—S—N—N torsion angles of −66.0 (3), −66.0 (3) and −58.4 (2)° for (I), (II) and (III), respectively. The hydrazone portions of the mol­ecules, S—N—N=C, are slightly twisted from planarity, with a torsion angle of 166.5 (3)° in (I), 165.4 (3)° in (II) and 157.9 (2)° in (III). The two aromatic rings present in the compounds are inclined to each other by 78.4 (2), 74.8 (2) and 76.9 (1)° in (I), (II) and (III), respectively. In the crystal structure of the parent compound (I), and of the ortho-methyl derivative (II), an N—H⋯O hydrogen bond links the mol­ecules into chains along [001], which are inter­connected by weak inter­molecular C—H⋯O inter­actions, generating layers lying parallel to the bc plane. In the crystal of the para derivative (III), however, the packing is significantly different. Here mol­ecules are linked by pairs of N—H⋯O hydrogen bonds, forming inversion dimers with an R ₂ ²(8) ring motif. The dimers are then linked by C—Cl⋯π inter­actions, forming ribbons propagating along [10]. Hirshfeld surface analyses show that the van der Waals inter­actions constitute the major contribution to the inter­molecular inter­actions in the crystal structures of all three compounds. The fingerprint plots indicate that the H⋯H contacts make the largest contributions to the Hirshfeld surfaces.

Chemical context  

Schiff bases are an important class of compounds in the field of coordination chemistry and catalysis (Mahfouz et al., 2015 ▸). The photochromic and thermochromic properties of Schiff bases make their study inter­esting (Girisha et al., 2018 ▸). They form second-order NLO organic materials, which are being used in computers, optical communication and medical imaging (Zarei et al., 2015 ▸). Hydrazones also play an important role in curing diseases effectively with less toxicity. Sulfonyl hydrazones are known for their good enzymatic modulation, analgesic, anti-Alzheimer’s, anti­depressant and anti­diabetic activities (Cunha et al., 2016 ▸). To investigate the impact of substitution, and also the variation of the site of substituent, on the structural parameters and the hydrogen-bonding inter­actions, we report herein on the synthesis and crystal structures of (E)-N′-(benzyl­idene)-4-chloro­benzene­sulfono­hydrazide (I) and its ortho- and para-methyl­substituted benzyl­idene derivatives, (II) and (III), respectively.

Structural commentary  

The title hydrazide (I) and its derivatives, (II) and (III), crystallize in the monoclinic crystal system with space group P2₁/c for (I) and (II) and P2₁/n for (III). The mol­ecular structures of compounds (I), (II) and (III) are illustrated in Figs. 1 ▸, 2 ▸ and 3 ▸, respectively. All three mol­ecules adopt an E configuration about the C=N bond of the central imine group. In the ortho-methyl-substituted derivative (II), the N—H and C—H bonds in the hydrazide part are anti with respect to the methyl substituent. These parts of the mol­ecules, S—N—N=C, show similar bond lengths of 1.258 (5), 1.272 (5) and 1.273 (3) Å for C7=N2 and 1.394 (5), 1.407 (5) and 1.393 (2) Å for N1—N2 in compounds (I), (II) and (III), respectively. These bond lengths are consistent with the C=N double-bond and N—N single-bond lengths, respectively. Furthermore, the S—N—N=C segments are slightly twisted from planarity, with torsion angles of 166.5 (3)° in (I), 165.4 (3)° in (II) and 157.9 (2)° in (III). All three compounds are bent at the S atom with C—S—N—N torsion angles of −66.0 (3), −66.0 (3) and −58.4 (2)° for (I), (II) and (III), respectively. The two aromatic rings present in these compounds are inclined to each other by 78.4 (2), 74.8 (2) and 76.9 (1)° in (I), (II) and (III), respectively. Hence the conformations of (I) and (II) are very similar while that of (III) is slightly different.

Supra­molecular features  

In the crystals of all three compounds, an O atom of the sulfonyl group acts as an acceptor and the amino H atom of the hydrazide segment as a donor in N—H⋯O hydrogen-bonding inter­actions with neighbouring mol­ecules (Tables 1 ▸, 2 ▸ and 3 ▸). The patterns of the hydrogen-bonding inter­actions in the crystal structures of (I) and (II) are very similar, and will be illustrated for compound (II) only. The N—H⋯O hydrogen-bonding inter­actions result in a C(4) graph-set motif generating chains propagating along the c-axis direction (Fig. 4 ▸). These chains are linked by weak C—H⋯O inter­actions involving an aromatic H atom of the benzyl­idenephenyl ring and a sulfonyl O atom, resulting in the formation of layers lying parallel to the bc plane (Tables 2 ▸ and 3 ▸, and Fig. 5 ▸). On changing the position of the methyl substituent from ortho- to para- the crystal packing changes significantly. Mol­ecules are now linked by pairs of N—H⋯O hydrogen bonds, forming inversion dimers enclosing (8) loops (Fig. 6 ▸, Table 3 ▸). The dimers are linked by a C—Cl⋯π inter­action, forming ribbons that propagate along the [10] direction (Fig. 6 ▸, Table 3 ▸).

Hirshfeld Surface analysis  

The nature of the inter­molecular contacts and their qu­anti­tative contributions to the crystal packing in all the three title compounds were analysed by Hirshfeld surface analysis and two-dimensional fingerprint plots, generated using CrystalExplorer3.1 (McKinnon et al., 2004 ▸; Spackman & Jayatilaka, 2009 ▸; Wolff et al., 2012 ▸). The Hirshfeld surfaces of the three compounds mapped over d _norm are shown in Fig. 7 ▸. The N—H⋯O inter­actions between the corresponding donor and acceptor atoms are visualized as bright-red spots and represent the short inter­atomic inter­actions in the crystal structures. The presence of two other light-red spots in (I) and (II) correspond to the C—H⋯O inter­actions, which are considered to be weak inter­actions.

Figure 7.

The two-dimensional fingerprint plots for the contacts H⋯H, C⋯H/H⋯C, O⋯H/H⋯O, Cl⋯H/H⋯Cl, C⋯C and N⋯H/H⋯N are illustrated in Figs. 8 ▸ and 9 ▸, for (I) and (III), respectively. The fingerprint plots of various contacts and their percentage contribution to the Hirshfeld surfaces are similar in (I) and (II) but, as expected, different from those for (III) (see Table 4 ▸). H⋯H contacts are the major contributors to the Hirshfeld surface: 30.1% in (I), 34.0% (II) and 38.0% in (III). The C⋯H/H⋯C contacts make the second largest contribution, i.e. 22.7, 20.2 and 18.0% for (I), (II) and (III), respectively. This is followed by O⋯H/H⋯O contacts arising from N—H⋯O and C—H⋯O inter­actions, contributing 16.1% in (I) and (II), and 15.7% in (III). N⋯H/H⋯N contacts arising from O—H⋯N hydrogen bonds contribute 6.3, 5.2 and 3.9%, respectively, in (I), (II) and (III). Cl⋯H/H⋯Cl inter­actions make a relatively significant contribution to the total Hirshfeld surfaces, comprising 12.1% in (I), 12.3% in (II) and 9.4% in (III). The C⋯C contacts representing π–π inter­actions contribute 5.2, 5.0 and 2.1% in (I), (II) and (III), respectively. Cl⋯O/O⋯Cl contacts comprise 5.0% in (I), 4.8% in (II) and 2.3% in (III). Weak Cl⋯Cl, C⋯O/O⋯C and C⋯S/S⋯C inter­actions are also observed; however, they exhibit minimal respect contributions of 0.5, 1.0 and 0% in (I), 0.5, 1.0, 0.1% in (II) and 0, 2.6 and 0.1% in (III), reflecting negligible or no effect on the mol­ecular packing.

Contact type	(I)	(II)	(III)
H⋯H	30.1	34.0	38.0
C⋯H/H⋯C	22.7	20.2	18.0
O⋯H/H⋯O	16.1	16.1	15.7
Cl⋯H/H⋯Cl	12.1	12.3	9.4

C⋯O/O⋯C	1.0	1.0	2.6
Cl⋯Cl	0.5	0.5	0
C⋯S/S⋯C	0	0.1	0.1

The most significant difference for compounds (I) and (II) compared to compound (III) is the presence of a relatively strong Cl⋯C/C⋯Cl inter­action in (III), in accordance with the C—Cl⋯π inter­action in the crystal (Table 3 ▸), which makes a contribution of 5.3%, while for (I) and (II) this inter­action is not present.

Database survey  

The crystal structures of (E)-N′-(4-chloro­benzyl­idene)-4-methyl­benzene­sulfono­hydrazide (IV) (Balaji et al., 2014 ▸) and N′-[(E)-4-methyl­benzyl­idene]4-methyl­benzene­sulfono­hydra­zide (V) (Tabatabaee et al., 2007 ▸) have been reported. They exhibit an E configuration with respect to the C=N bond and an almost perpendicular orientation of the two aromatic rings with dihedral angles of 81.9 (3)° in (IV) and 82.4 (1)° in (V), very similar to the values of 78.4 (2), 74.8 (2) and 76.9 (1)° in (I), (II) and (III), respectively. In the structures of these related compounds (I)–(V) and also those of benzyl­idene, 3,3-di­phenyl­allyl­idene (Mehrabi & Kia, 2009 ▸; Mehrabi et al., 2008 ▸), 4-bromo/5-bromo-2-hy­droxy/5-chloro-2-hy­droxy (Kia et al., 2008a ▸,b ▸) and 2-hy­droxy-5-iodo (Ghorbanloo & Notash, 2012 ▸) derivatives of p-toluene­sulfono­hydrazide, the aryl­sulfono­hydrazide mol­ecules are directly connected to one another via significant N—H⋯O hydrogen-bonding inter­actions involving a sulfonyl oxygen atom and the amino hydrogen atom.

Synthesis and crystallization  

Synthesis of 4-chloro­benzene­sulfono­hydrazide

To 4-chlro­benzene­sulfonyl chloride (0.01 mol) dissolved in propanol (30 ml), 99% hydrazine hydrate (5 ml) was added at 273 K under constant stirring. The stirring continued for 15 min at 273 K and then at 303 K for 3 h. After completion of the reaction (monitored by TLC), the reaction mixture was concentrated by evaporating the excess propanol. The solid product, 4-chloro­benzene­sulfono­hydrazide was washed with cold water and dried.

Synthesis of compounds (I), (II) and (III)

The parent, ortho- and para- substituted (E)-N′-(benzyl­idene)-4-chloro­benzene­sulfono­hydrazides (I), (II) and (III), were synthesized by refluxing mixtures of 4-chloro­benzene­sulfono­hydrazide (0.01 mol) and benzaldehyde, 2-methyl-benzaldehyde or 4-methyl­benzaldehyde (0.01 mol), respect­ively, in ethanol (30 ml) and two drops of glacial acetic acid for 4 h. The reaction mixtures were cooled to room temperature and concentrated by evaporating the excess of solvent. The solid products (I), (II) and (III) obtained were washed with cold water, dried and recrystallized to constant melting points from ethanol to obtain the pure compounds. The purity of the compounds was checked by TLC. Single crystals of the hydrazides suitable for single crystal X-ray diffraction analysis were obtained by slow evaporation of their DMF solutions at room temperature. All three compounds were characterized by measuring their IR, ¹H and ¹³C NMR spectra.

Refinement  

Crystal data, data collection and structure refinement details are summarized in Table 5 ▸. For all three compounds, the H atom of the NH group was located in difference-Fourier maps and later restrained to N—H = 0.86 (2) Å. C-bound H atoms were positioned with idealized geometry and refined using a riding model: C—H = 0.93–0.96 Å with U _iso(H) = 1.5U _eq(C-meth­yl) and 1.2U _eq(C-aromatic, N) for other H atoms. The U^ij components of C9, C10, C11 and C12 in (I) and C10, C11, C12 and C13 in (II) and (III) were restrained to approximate isotropic behaviour.

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.

(E)-4-Chloro-N'-(2-methylbenzylidene)benzenesulfonohydrazide (II) . 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.

(E)-4-Chloro-N'-(4-methylbenzylidene)benzenesulfonohydrazide (III) . 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.
