Different packing motifs of isomeric (E)-N'-(halo-phenyl-methyl-idene)-N-methyl-2-(thio-phen-2-yl)acetohydrazides controlled by C-H⋯O inter-actions.

The crystal structures of three isomeric (E)-N'-(chloro-phenyl-methyl-idene)-N-methyl-2-(thio-phen-2-yl)acetohydrazides (C14H13ClN2OS) are described, with the Cl atom in ortho (I), meta (III) and para (IV) positions in the benzene ring. The ortho-bromo derivative (II) (C14H13BrN2OS), which is isostructural with its chloro congener (I), is also reported. Mol-ecules (I)-(III) have similar conformations, which approximate to l-shapes, as indicated by their N-C-C-Ct (t = thio-phene) torsion angles of -90.1 (3), -91.44 (18) and -90.7 (9)°, respectively. The conformation of (IV) is different, with an equivalent torsion angle of -170.75 (11)° corresponding to a more extended shape for the mol-ecule. The thio-phene ring in each structure features 'flip' rotational disorder. The packing for (I) and (II) features inversion dimers, linked by pairs of C-H⋯O inter-actions, which generate R22(14) loops. In the crystal of (III), [010] C(8) chains arise, with adjacent mol-ecules linked by pairs of C-H⋯O hydrogen bonds. The packing for (IV) features unusually short C-H⋯O inter-actions arising from an H atom attached to the benzene ring (H⋯O = 2.18 Å), which lead to C(9) [301] chains. Hirshfeld fingerprint percentage contact contributions are similar for the four title compounds.

Chemical context

We have reported the syntheses and anti-TB activities of acetamido derivatives, 2-(R,R′NCOCH2)-thio­phene, R = alkyl (Nora de Souza et al., 2008 ▸), and more recently thienyl aceto­hydrazide derivatives, 2-(ArCH=N—NHCOCH2)-thio­phene (Cardoso et al., 2014 ▸). We are now studying the related family of methyl­ated 2-[ArCH=N—Nn class="Chemical">(CH3)COCH2]-thio­phene compounds, with different substituents attached to the benzene ring. The biological activities of these compounds will be reported elsewhere: here, we present the crystal structures of three isomeric chloro derivatives (and one bromo derivative) in this family bearing a halogen atom at different sites on the benzene ring, viz. (E)-N′-(2-chloro­phenyl­methyl­idene)-N-methyl-2-(thio­phen-2-yl)acetohydrazide (I), (E)-N′-(2-bromo­phenyl­methyl­idene)-N-methyl-2-(thio­phen-2-yl)acetohydrazide (II), (E)-N′-(3-chloro­phenyl­methyl­idene)-N-methyl-2-(thio­phen-2-yl)acetohydrazide (III) and (E)-N′-(4-chloro­phenyl­methyl­idene)-N-methyl-2-(thio­phen-2-yl)acetohydrazide (IV). These complement our recent structural study (Cardoso et al., 2016a ▸) of isomeric ortho-, meta- and para-nitro derivatives in the same family.

Structural commentary

The mol­ecular structure of (I) is shown in Fig. 1 ▸, which indicates that the expected methyl­ation has occurred at atom N2. The thio­phene ring (S1/C11–C14) shows ‘flip’ disorder (compare, for example, Sonar et al., 2005 ▸; Wagner et al., 2006 ▸) over two conformations rotated by ∼180° about the C10—C11 bond in a 0.658 (4):0.342 (4) ratio: the major orientation has the S atom pointing towards the C1–C6 n class="Chemical">benzene ring at the other end of the mol­ecule. The dihedral angle between the thio­phene and benzene rings is 77.92 (8)°. The central CH=N—N(CH3)—C(=O) fragment (C7/C8/C9/N1/N2/O1) in (I) is almost planar (r.m.s. deviation = 0.013 Å) and subtends dihedral angles of 0.89 (12) and 78.80 (9)° with the benzene and thio­phene rings, respectively. Thus, the major twist in the mol­ecule occurs about the C9—C10 bond [N2—C9—C10—C11 = −90.1 (3)°], giving the mol­ecule an approximate overall L-shape. The N1—N2 bond length of 1.372 (3)° is significantly shortened compared to the reference value of ∼1.41 Å for an isolated N—N single bond and the C9—N2 amide bond of 1.377 (3) Å is clearly lengthened: these data can be inter­preted in terms of significant delocalization of electrons over the methyl­idene–acetohydrazide group.

The mol­ecular structure of (I), showing 50% probability displacement ellipsoids. Only the major orientation of the thio­phene ring is shown.

Compound (II) (Fig. 2 ▸) is isostructural with (I); comparable geometrical data are as follows: C1–C6 benzene ring = ‘A’, thio­phene ring = ‘B’ [disorder occupancies = 0.677 (3):0.323 (3)], linking chain (r.m.s. deviation = 0.009 Å) = ‘C’; dihedral angles A/B, A/C and B/C = 75.89 (5), 1.53 (8) and 77.37 (6)°, respectively; n class="Chemical">N2—C9—C10—C11 = −91.44 (18)°, N1—N2 = 1.3720 (19) Å and C9—N2 = 1.375 (2) Å. These data are very similar to the corresponding values for (I); the only significant (and expected) difference is the C6—Br1 bond length of 1.9064 (16) Å in (II) compared to the C6—Cl1 distance of 1.748 (3) Å in (I).

The mol­ecular structure of (III) can be seen in Fig. 3 ▸: again the methyl­ation of N2 has occurred as expected. The dihedral angle between the thio­phene ring [rotationally n class="Disease">disordered over two orientations in a 0.81 (1):0.19 (1) ratio] and the C1–C6 benzene ring is 66.0 (2)°. The approximately planar central C7/C8/C9/N1/N2/O1 group in (II) (r.m.s. deviation = 0.043 Å) subtends dihedral angles of 5.9 (5)° with the benzene ring and 62.9 (3)° with the thio­phene ring. As in (I) and (II), the major twist occurs about the C9—C10 bond [N2—C9—C10—C11 = −90.7 (9)°], giving the mol­ecule an approximate overall L-shape. The N1—N2 and C9—N2 bond lengths in (III) are 1.379 (9) and 1.363 (11) Å, respectively, which again can be ascribed to electronic effects.

The mol­ecular structure of (III), showing 50% probability displacement ellipsoids. Only the major orientation of the thio­phene ring is shown.

As with the other compounds, (IV) is methyl­ated at N2 (Fig. 4 ▸) and has a n class="Disease">disordered thio­phene ring [major/minor disorder components = 0.671 (2):0.329 (2)]. The dihedral angles between the benzene ring ‘A’, thio­phene ring ‘B’ and CH=N—N(CH3)—C(=O)—CH2 fragment ‘C’ (r.m.s. deviation = 0.031 Å), are A/B = 81.82 (4), A/C = 14.79 (4) and B/C = 69.70 (5)°. These are roughly consistent with the equivalent data for (I)–(III), but the conformation of (IV) is definitely different, as indicated by the N2—C9—C10—C11 torsion angle of −170.75 (11)°: this reflects the fact that the thio­phene ring points away from the rest of the mol­ecule. Bond-length data [N1—N2 = 1.3778 (14) Å and C9—N2 = 1.3693 (16) Å] within the methyl­idene–acetohydrazide group for (IV) are consistent with the equivalent data for (I), (II) and (III).

Supra­molecular features

The packing motifs in (I) and (II) feature inversion dimers linked by pairs of C—H⋯O inter­actions (Fig. 5 ▸; Tables 1 ▸ and 2 ▸), with the C—H grouping part of the thio­phene ring: this generates an (14) loop. Weak C—H⋯π inter­actions consolidate the structures, but there are no aromatic π–π stacking inter­actions [minimum centroid–centroid separation = 4.86 Å for (I) and 4.85 Å for (II)].

The packing in (III) features two C—H⋯O inter­actions (Table 3 ▸) arising from benzene and adjacent methine C—H groups, which link the mol­ecules into [010] chains (Fig. 6 ▸), with adjacent mol­ecules in the chain related by the 21 screw axis in the b direction. The C6 inter­action is long, but deemed to be just significant, as it is consolidating the C7 bond. Individually, each C—H⋯O bond generates a C(8) chain; collectively (6) loops arise. A very weak C—H⋯Cl bond is also observed. There are no C—H⋯π contacts in (III) and we consider that the shortest ring-centroid separation of 4.219 (5) Å is far too long to be regarded as a bonding inter­action.

In the crystal of (IV), an unusually short C—H⋯O inter­action (Table 4 ▸) with H⋯O = 2.18 Å leads to C(9) chains (Fig. 7 ▸) propagating in the [301] direction. The acceptor O atom deviates from the plane of Cl1/C4/C5/H5 by 0.239 (6) Å. One reason for the short contact could be the presence of the adjacent electron-withdrawing Cl substituent, which will tend to ‘activate’ the H atom (Steiner, 1996 ▸). Two extremely weak C—H⋯Cl inter­actions and a C—H⋯π contact occur, but there is no π–π stacking (minimum centroid–centroid separation = 4.42 Å) in the crystal of (IV).

Hirshfeld surface fingerprint plots for (I)–(IV) (supplementary Figs. 1 ▸–4 ▸ ▸ ▸) were calculated with CrystalExplorer17 (Turner et al., 2017 ▸) and percentage contact-surface contributions (McKinnon et al., 2007 ▸) are listed in Table 5 ▸. As might be expected, the percentage contact data for the isomeric (I) and (II) are very similar but it is inter­esting that the data for (III) and (IV) barely differ from those of the first two compounds, despite their different crystal structures: in every case H⋯H contacts dominate the packing. This is quite different to the recently reported (E)-N′-(3-cyano­rophenyl­methyl­idene)-N-methyl-2-(thio­phen-2-yl)acetohydrazide (V) and (E)-N′-(4-meth­oxy­n class="Chemical">phenyl­methyl­idene)-N-methyl-2-(thio­phen-2-yl)acetohydrazide (VI) (Cardoso et al., 2017 ▸), where the percentage contributions of the different inter­molecular contacts to the fingerprint plots differ by up to 20%.

Database survey

A survey of the Cambridge Structural Database (Groom et al., 2016 ▸) updated to June 2017 for the common central —CH=N—N(CH3)—C(=O)—CH2— fragment of the title compounds revealed seven matches, viz. ALAHEC (Cardoso et al., 2016b ▸); FOTMUX (Ramírez et al., 2009a ▸); KULREP (Ramírez et al., 2009b ▸); OFEBIL (Cao et al., 2007 ▸), and EYUBAD, EYUBEH and EYUBIL; this latter trio of refcodes correspond to the three isomeric n class="Chemical">nitro compounds (Cardoso et al., 2016a ▸) noted in the Chemical Context section above. To this list will soon be added the structures of (V) and (VI) noted above.

Synthesis and crystallization

The appropriate thienyl acetohydrazide derivative (Cardoso et al., 2014 ▸) (0.20 g, 1.0 equiv.) was suspended in n class="Chemical">acetone (5 ml) and potassium carbonate (4.0 equiv.) was added. The reaction mixture was stirred at room temperature for 30 min. and methyl iodide (4.0 equiv.) was added. The reaction mixture was maintained at 313 K, until thin-layer chromatography indicated the reaction was complete. The mixture was then rotary evaporated to leave a residue, which was dissolved in water (20 ml) and extracted with ethyl acetate (3 × 10 ml). The organic fractions were combined, dried with anhydrous MgSO4, filtered and the solvent evaporated at reduced pressure. The crystals used for the intensity data collections were recrystallized from methanol solution.

Refinement

Crystal data, data collection and structure refinement details are summarized in Table 6 ▸. H atoms were placed geometrically (C—H = 0.95–1.00 Å) and refined as riding atoms. The constraint U iso(H) = 1.2U eq(carrier) or 1.5U eq(meth­yl) was applied in all cases. The N-methyl group was allowed to rotate, but not to tip, to best fit the electron density (AFIX 137 instruction in SHELXL; Sheldrick, 2015 ▸); in every case, this group rotated from its intial calculated orientation to minimize steric inter­action with H7; the final optimized geometry leads to a short (H⋯O ∼ 2.35 Å) intra­molecular C8—H⋯O1 contact but we do not regard this as a bond. The thio­phene rings show ∼180° ‘flip’ rotational disorder about the C10—C11 bond for all compounds. The crystal of (III) used for data collection was small and data quality was poor. Iin the refinement, difference maps indicated significant unmodelled electron density in the vicinity of C4. This was modelled in terms of a minor n class="Disease">impurity/disorder component with the Cl atom bonded to C4 rather than C3. Even after the disorder modelling, the residuals are high, but we deem the refinement to be acceptable in terms of its chemical information content.

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.
