Expected and unexpected products of reactions of 2-hydrazinylbenzo-thia-zole with 3-nitro-benzene-sulfonyl chloride in different solvents.

The syntheses and crystal structures of 2-[2-(propan-2-yl-idene)hydrazin-yl]-1,3-benzo-thia-zol-3-ium 3-nitro-benzene-sulfonate (C10H12N2S+·C6H4NO5S-), (I), 2-[2-(3-nitro-benzene-sulfon-yl)hydrazin-yl]-1,3-benzo-thia-zole (C13H10N4O4S2), (II) and 2-[2-(3-nitro-benzene-sulfon-yl)hydrazin-yl]-1,3-benzo-thia-zol-3-ium 3-nitro-benzene-sulfonate (C13H11N4O4S2+·C6H4NO5S-), (III) are reported. Salt (I) arose from an unexpected reaction of 2-hydrazinylbenzo-thia-zole with the acetone solvent in the presence of 3-nitro-benzene-sulfonyl chloride, whereas (II) and (III) were recovered from the equivalent reaction carried out in methanol. The crystal of (I) features ion pairs linked by pairs of N-H⋯Os (s = sulfonate) hydrogen bonds; adjacent cations inter-act by way of short π-π stacking inter-actions between the thia-zole rings [centroid-centroid separation = 3.4274 (18) Å]. In (II), which crystallizes with two neutral mol-ecules in the asymmetric unit, the mol-ecules are linked by N-H⋯N and N-H⋯On (n = nitro) hydrogen bonds to generate [[Formula: see text]1[Formula: see text]] chains, which are cross-linked by C-H⋯O and π-π stacking inter-actions. The crystal of (III) features centrosymmetric tetra-mers (two cations and two anions) linked by cooperative N-H⋯O hydrogen bonds; C-H⋯O and π-π inter-actions occur between tetra-mers.

Chemical context

Heteroaromatic benzo­thia­zole derivatives are well-studied compounds, due in the main to their various and useful biological activities (for a review, see Gulati et al., 2017 ▸), but also to their fluorescent and optical properties (e.g. Liu et al., 2018 ▸). Hydrazonyl derivatives, 2-Ar—CH=n class="Chemical">N—NH-benzo­thia­zoles, formed from 2-hydrazinylbenzo­thia­zole and ArCHO have attracted attention: for example, Katava et al. (2017 ▸) have reported anti­tumor activities and Behera & Manivannan (2017 ▸) studied their use as sensors. Less attention has been paid generally to 2-(ArSO2NHNH)-benzo­thia­zoles, although anti­microbial activities have been briefly reported (Rao et al., 2005 ▸; Hipparagi et al., 2007 ▸).

We have initiated a study of the syntheses, structures and biological activities of 2-(ArSO2NHn class="Chemical">NH)-benzo­thia­zoles and we now describe the structures of three products of the reactions of 2-hydrazinylbenzo­thia­zole with 3-nitro­benzene­sulfonyl chloride in different solvents, viz. 2-[2-(propan-2-yl­idene)hydrazin­yl]-1,3-benzo­thia­zol-3-ium 3-nitro­benz­enesulfonate (I), 2-[2-(3-nitro­benzene­sulfon­yl)hydrazin­yl]-1,3-benzo­thia­zole (II) and 2-[2-(3-nitro­benzene­sulfon­yl)hydrazin­yl]-1,3-benzo­thia­zol-3-ium 3-nitro­benzene­sulfonate (III).

Structural commentary

Compound (I) crystallizes in space group P with one C10H12N3S+ cation (protonated at n class="Chemical">N1) and one C6H4NO5S− sulfonate anion in the asymmetric unit (Fig. 1 ▸). Evidently, the starting hydrazone has reacted with the acetone solvent (Day & Whiting, 1970 ▸) to generate an N-propyl­idine group; at the same time, the sulfonyl chloride has been hydrolysed to sulfonic acid and a mol­ecular salt has crystallized after proton transfer from the sulfonic acid to the N atom of the thia­zole ring. The cation is close to planar; the dihedral angle between the benzo­thia­zole ring system (r.m.s. deviation = 0.005 Å) and the N2/N3/C8/C9/C10 grouping (r.m.s. deviation = 0.004 Å) is 7.89 (10)°; the C7—N2—N3—C8 torsion angle is −172.8 (2)°. The C8—N3 bond length of 1.278 (4) Å is fully consistent with double-bond character. In the anion, the nitro group is twisted by 26.7 (4)° with respect to the benzene ring. As expected, the S—O bond lengths of the sulfonate group are almost the same, indicating the usual delocalization of the negative charge and the same situation is found in compound (III) described below.

Compound (II) represents the expected condensation product of the starting hydrazone and n class="Chemical">sulfonyl chloride and crystallizes with two neutral C13H10N4O4S mol­ecules in the asymmetric unit (Fig. 2 ▸) in space group P . In the first (S1) mol­ecule, the dihedral angle between the benzo­thia­zole ring system (r.m.s. deviation = 0.013 Å) and the C8 benzene ring is 32.59 (4)°; the nitro group is twisted by 0.68 (7)° from the C8 benzene ring. The C7—N2—N3—S2 torsion angle is −99.88 (12) and the H2—N2—N3—H3 torsion angle is −54 (2)°. The bond-angle sum at N2 is 359.9°, indicative of sp 2 hybridization, whereas the corresponding value for N3 of 341.1° points towards substantial sp 3 hybrid character. The C7—N2 bond length of 1.3529 (16) Å is short for a nominal single bond, presumably indicative of conjugation of the N2 nominal lone pair of electrons with the adjacent ring system. In the second (S3) mol­ecule, the corresponding geometrical data are 0.008 Å (r.m.s. deviation for S3 ring system), 30.01 (3)° (S3/C21 rings), 3.46 (13)° (nitro group and C21 ring), −103.53 (12)° (C20—N6—N7—S4), −50.3 (18)° (H6—N6—N7—H7), 359.9° (bond-angle sum at N6), 341.7° (bond-angle sum at N7) and 1.3549 (16) Å (C20—N6 bond length). All-in-all, the S1 and S3 mol­ecules have similar conformations as indicated by the r.m.s. overlay fit of 0.221 Å for their non-hydrogen atoms.

Compound (III), which was recovered from the same reaction as (II), represents the same condensation product, which has gone on to further react with a hydrolysed sulfonyl chloride species to form a mol­ecular n class="Chemical">salt (proton transfer to N1). Once again, the space group is P and one cation and one anion (Fig. 3 ▸) make up the asymmetric unit. The benzo­thia­zole ring system (r.m.s. deviation = 0.005 Å) subtends a dihedral angle of 57.54 (3)° with the C8 benzene ring and the nitro group is twisted from its attached ring by 4.8 (3)°. The C7—N2—N3—S2 and H2—N2—N3—H3 torsion angles are −110.54 (12) and −48.5 (19)°, respectively. The bond-angle sums at N2 and N3 are 359.0 and 339.1°, respectively, and the same conclusions re hybridization states for these atoms as in (II) may be drawn. This is backed up by the shortened C7—N2 bond length of 1.3317 (17) Å in (III) compared to (II). presumably because resonance is enhanced by the positive charge on N1. In the anion, the nitro group is twisted from its attached ring by 17.7 (2)°.

Supra­molecular features

In the crystal of (I), the cation and the anion are linked by a pair of N—H⋯O n class="Chemical">hydrogen bonds (Table 1 ▸), which generate an (8) loop. The ion pairs are connected by various weak C—H⋯O inter­actions, with the acceptor O atoms being parts of the sulfonate and nitro groups. No C—H⋯π inter­actions could be identified in the crystal of (I) but aromatic π–π stacking inter­actions are seen, with the shortest centroid–centroid separation of 3.4274 (18) Å (slippage = 0.729 Å) occurring between inversion-related pairs of thia­zole rings (Fig. 4 ▸); atom N2 of the hydrazone group lies above the benzene ring (Cg⋯N2 = 3.385 Å) and possibly provides some additional stabilization. Taken together, the directional inter­molecular inter­actions in (I) generate a three-dimensional network.

The dominant inter­molecular inter­actions in (II) are N—H⋯n class="Chemical">N and N—H⋯O hydrogen bonds (Table 2 ▸); the first of these (N2—H2⋯N5 and N6—H6⋯N1) occur in the arbitrarily chosen asymmetric unit to link the mol­ecules into dimers that ‘slot together’: the dihedral angle between the benzo­thia­zole planes in the two mol­ecules is 36.06 (4)° and the pendant benzene sulfonyl groups project to the same side of the ensemble. The N—H⋯On (n = nitro) links connect the dimers into infinite [1] chains (Fig. 5 ▸). A number of weak C—H⋯O inter­actions are also observed, which serve to cross-link the chains. Several π–π stacking contacts occur in the crystal of (II), with the shortest [centroid–centroid separation = 3.5186 (7)Å] occurring between the C8–C13 and C14–C19 rings. Finally, a short N8—O7⋯π (π = centroid of the C21–C26 benzene ring) contact is observed with N⋯π = 3.2497 (12) Å and N—O⋯π = 86.24 (8)°.

The packing in (III) features a pair of cation-to-anion N—H⋯O links from n class="Chemical">N1 and N2 (Table 3 ▸), which is essentially the same motif as seen in (I). The N3—H3 grouping links to a symmetry-generated sulfonate O atom and a centrosymmetric tetra­mer (two cations and two anions) results (Fig. 6 ▸). A pair of weak C—H⋯O inter­actions helps to provide cohesion between tetra­mers in the crystal and π–π stacking is also observed, with the shortest centroid–centroid separation being 3.6743 (8) Å between the thia­zole and C1–C6 rings.

Database survey

A survey of of the Cambridge Structural Database (Groom et al., 2016 ▸: updated to March 2018) for benzo­thia­zole hydrazones revealed the prototype compound, benzo­thia­zol-2-yl-hydrazine (refcode: n class="Chemical">NAPKAR; Rajnikant et al., 2005 ▸) as well as three derivatives with various substituents attached to the benzene ring, viz. EVARID (Liu et al., 2011 ▸), LAPCAI (Fun et al., 2012a ▸) and LEFTEX (Fun et al., 2012b ▸). No hits for benzene­sulfonyl­hydrazino-benzo­thia­zoles were recorded.

Synthesis and crystallization

To prepare (I), a mixture of 2-hydrazinylbenzo­thia­zole (1.00 mmol) and 3-nitro­n class="Chemical">benzene­sulfonyl chloride (1.00 mmol) in acetone (15 ml) was gently heated at 313–323 K for 30 minutes, then rotary evaporated and the residue was recrystallized by slow evaporation from methanol solution at room temperature; m.p. 444–445 K. ESI–HRMS (M + H). Calculated: 206.0752 for C10H12N3S, found: 206.0755. IR: 2930(br), 1621, 1530, 1350, 1241, 1151, 1028 cm−1

Compounds (II) and (III) arose from the same reaction: a solution of 2-hydrazinylbenzo­thia­zole (1.00 mmol) and 3-nitro­n class="Chemical">benzene­sulfonyl chloride (1.00 mmol) in methanol (15 ml) was gently heated at 313–323 K for 30 minutes, then rotary evaporated and the residue was recrystallized by slow evaporation from methanol solution at room temperature. A mixture of two distinct crystalline products, one yellow [compound (II)] and the other colourless [compound (III)], was isolated. These were separated by eye, and each product was futher recrystallized from methanol solution. (II); m.p. 442–444 K. ESI–HRMS (M − H).

Refinement

Crystal data, data collection and structure refinement details are summarized in Table 4 ▸. The N-bound n class="Chemical">hydrogen atoms were located in difference maps and their positions freely refined. The C-bound hydrogen atoms were geometrically placed (C—H = 0.95–0.98 Å) and refined as riding atoms. The constraint U iso(H) = 1.2U eq(carrier) or 1.5U eq(methyl carrier) was applied in all cases. The methyl groups in (I) were allowed to rotate, but not to tip, to best fit the electron density.

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.

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.

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.
