Crystal structure of N'-[2-(benzo[d]thia-zol-2-yl)acet-yl]-4-methyl-benzene-sulfono-hydrazide.

In the title compound, C16H15N3O3S2, the hydrazide N atom bonded to the C=O group is planar, whereas that bonded to the SO2 group is pyramidally coordinated. The inter-planar angle between the ring systems is 40.71 (3)°. Mol-ecules are connected into ribbons parallel to the b axis by two classical hydrogen bonds N-H⋯O=C and N-H⋯Nthia-zole.

Chemical context

Benzo­thia­zoles are versatile heterocyclic compounds with potential pharmaceutical applications (Elgemeie & Aal, 1986 ▸). Various benzo­thia­zoles have been used as anti-inflammatory, anti­microbial and analgesic agents and as laser dyes (Elgemeie, 1989 ▸). This has led to an increasing inter­est in benzo­thia­zole derivatives in the area of drug design and discovery (Elgemeie et al., 2000 ▸). As a part of our research work on new syntheses of benzo­thia­zoles as chemotherapeutic agents (Elgemeie et al., 2017 ▸), we have previously reported the synthesis of 2-aryl­benzo­thia­zoles that later found applications as anti­cancer agents and are presently in clinical use for various diseases (Elgemeie & Elghandour, 1990 ▸). We report here the new compound N′-(2-(benzo[d]thia­zol-2-yl)acet­yl)-4-methyl­benzene­sulfono­hydrazide (1), which was prepared by the reaction of 2-(benzo[d]thia­zol-2-yl)acetohydrazide with p-toluene­sulfonyl chloride in the presence of pyridine at room temperature. The structure of (1) was determined on the basis of its spectroscopic data and elemental analysis (see Experimental). In order to establish the structure of the product unambiguously, its crystal structure was determined.

Structural commentary

The X-ray analysis confirms the exclusive presence of the form (1) in the solid state (Fig. 1 ▸). The mol­ecular dimensions may be regarded as normal (Table 1 ▸); the torsion angles defining the conformation of the chain connecting the ring systems are also given in this Table. The bond lengths C2—S1 and C2—N3 in the heterocycle correspond well with the average values of 1.750 (15) and 1.200 (14) Å found in the Cambridge Structural Database (Version 5.38; Groom et al., 2016 ▸) for 375 examples of this ring system (unsubstituted benzo ring, carbon-substituted at C2). Nitro­gen N1 displays a planar geometry, whereas N2 is pyramidal [they lie 0.014 (7) and 0.337 (8) Å, respectively, outside the plane of their substituents]. Hydrogen atom H01 is anti­periplanar to O3 and H02 to O2 across the N1—C9 and N2—S2 bonds, respectively. The inter­planar angle between the ring systems is 40.71 (3)°.

Supra­molecular features

Mol­ecules are connected by two pairs of classical hydrogen bonds across inversion centres, to form ribbons parallel to the b axis (Table 2 ▸, Fig. 2 ▸). A C—H⋯O inter­action connects the mol­ecules by c-axis translation (not shown in the Figure), forming layers parallel to (100).

Database survey

A search of the Cambridge Database (Version 5.38; Groom et al., 2016 ▸) for the substructure Ar—SO2—NH—NH—C(=O)—C gave six hits: EYOZIB, KUKYOG, XOVFEV, XOZDOG, YOTKAU and ZIVVUX.

Synthesis and crystallization

A solution of p-toluene­sulfonyl chloride (1.90 g, 0.015 mol) in pyridine (10 ml) was added gradually to a stirred solution of 2-(benzo[d]thia­zol-2-yl)acetohydrazide (2.07 g, 0.01 mol) in pyridine (10 ml) at 273 K. The reaction mixture was then stirred at room temperature for 3 h (TLC control). After the reaction was completed, the mixture was poured into ice-water with continuous stirring and neutralized with 1 N HCl solution to pH 7. The precipitate thus formed was filtered off, washed with water and recrystallized from ethanol to give colourless crystals (yield 85%; m.p. = 458 K). IR (KBr, cm−1): ν 3427 (NH), 3164 (Ar CH), 2929, 2858 (CH3, CH2), 1692 (C=O); 1H NMR (400 MHz, DMSO-d 6): δ 2.26 (s, 3H, CH3), 3.95 (s, 2H, CH2), 7.15 (d, J = 8 Hz, 2H, SO2C6H4), 7.44 (t, J = 8 Hz, 1H, benzo­thia­zole H), 7.52 (t, J = 8 Hz, 1H, benzo­thia­zole H), 7.62 (d, J = 8 Hz, 2H, SO2C6H4), 7.96 (d, J = 8 Hz, 1H, benzo­thia­zole H), 8.07 (d, J = 8 Hz, 1H, benzo­thia­zole H), 9.95 (s, 1H, NH), 10.52 (s, 1H, NH).

Refinement

Crystal data, data collection and structure refinement details are summarized in Table 3 ▸. NH hydrogen atoms were refined freely. The methyl hydrogen atoms were not well defined and so were refined as a hexa­gon of half-occupied sites with C—H = 0.98 Å (AFIX 127). Other hydrogen atoms were included using a riding model starting from calculated positions (C—Haromatic = 0.95, C—Hmethyl­ene 0.99 Å) with U iso(H) = 1.2U eq(C).

Despite the slightly larger ellipsoid of the benzo­thia­zol sulfur atom S1, there is no evidence for significant mixing (disorder) of the sites N3/S1.

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.
