In the title solvate, C30H24N4O2S·CH3CN, the substituted thiophene possesses approximate Cs(m) intrinsic symmetry, with the mirror plane passing through the S atom and the mid-point of the (Ph)C-C(Ph) bond. Despite the main backbone of the molecule being a long chain of conjugated bonds, it adopts a non-planar conformation due to the presence of various intra- and intermolecular hydrogen bonds. The hydrogen bonds result in twist configurations for both the amido and aminophenyl fragments relative to the central thiophene ring. There are two intramolecular Namine-H
O hydrogen bonds within the thiophene-2,5-dicarboxamide molecule that form seven-membered rings. In the crystal, the thiophene-2,5-dicarboxamide molecules form inversion dimers by four amide-amine N-H
N hydrogen bonds. The dimers are further linked into layers propagating in (100) both directly (via Namine-H
O hydrogen bonds) and through the acetonitrile solvate molecules (via amine-cyano N-H
N and CMe-H
O interactions).
2,5-Bis((2-thio-1,3-thiazolidine-3-yl)carbonyl)-3,4-diphenylthiophene (II). 3,4-Diphenylthiophene-2,5-dicarboxylic acid (9 g, 27.7 mmol) was suspended in 35 ml freshly distilled SOCl2 in the presence of several drops of DMF. The resulting mixture was heated at reflux for 1 hour. The excess SOCl2 was removed under reduced pressure and the residue was further dried at 373 K under high vacuum. The thiophene diacid chloride obtained in this way was dissolved in 130 ml dry THF and added drop-wise during a 2 hour period to a solution containing 1,3-thiazolidine-2-thione (6.6 g, 55.4 mmol) and triethylamine (20 ml) in 330 ml dry THF. During this process carried out under continuous stirring the reaction temperature was kept at 323 K. After the addition was complete the reaction mixture was maintained under the same conditions for an additional 2 hours and then for a further 16 h at room temperature with stirring. The reaction mixture was then filtered, and the resulting solid was washed with cold THF. The filtrate was reduced in volume to a dark paste using a rotary evaporator. This paste-like material was then taken up into 30 ml of ethyl acetate. After this mixing procedure, crude product was filtered off as a dark-yellow powder. Recrystallization from dichloroethane yielded 10.8 g (74%) of yellow crystals. M.p. = 527-529 K. Found: C, 54.73; H, 3.44; N, 5.32. Calcd for C24H18N2O2S5: C, 54.98; H, 3.23; N, 5.36. 1H NMR (400 MHz, CDCl3): \d = 2.72 (t, 4H), 4.21 (t, 4H), 7.05 (m, 4H), 7.22 (m. 6H). 13C NMR (100 MHz, CDCl3): \d = 29.61, 55.80, 127.90, 127.99, 129.60, 134.21, 136.08, 144.34, 164.16, 200.37. Mass spectrometry (ESI+): 548.9 [M+Na]+, 1074.3 [2M+Na]+, 1601.8 [3M+Na]+.
(II) (5.0 g, 9.45 mmol) was added to a solution of 1,2-diaminobenzene (3.1 g, 28.4 mmol) in 125 ml of dry methylene chloride. The resulting mixture was stirred at room temperature for 2 days. At this juncture, the desired product, compound I, was obtained via filtration in a yield of 78% (3.7 g). M.p. = 501-503 K. Found: C, 71.40; H, 4.77; N, 11.45. Calcd for C30H24N4O2S: C, 71.41; H, 4.79; N, 11.10. 1H NMR (400 MHz, DMSO-d6): δ = 4.50 (s, 4H), 6.53 (t, 2H), 6.68 (d, 2H), 6.90 (t, 2H), 7.02 (d, 2H), 7.17 (m, 4H), 7.25 (m, 6H), 8.76 (s, 2H). 13C NMR (100 MHz, DMSO-d6): δ = 127.48, 127.90, 133.71, 136.90, 138.13, 139.58, 139.37, 141.32, 145.59, 147.12, 153.39, 153.48, 171.99. Mass spectrometry (ESI+): 527.1 [M+Na]+, 1030.9 [2M+Na]+, 1535.8 [3M+Na]+. Crystals suitable for X-ray diffraction were obtained by slow evaporation from an acetonitrile solution.
The hydrogen atoms of the amino-groups as well as the solvate acetonitrile molecule were localized in the difference-Fourier map and included in the refinement with fixed positional (C–H = 0.98 Å) and isotropic displacement parameters [Uiso(H) = 1.5Ueq(C) for CH3-group and Uiso(H) = 1.2Ueq(N) for amino groups]. The other hydrogen atoms were placed in calculated positions with C–H = 0.95 Å and refined in the riding model with fixed isotropic displacement parameters [Uiso(H) = 1.2Ueq(C)].

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 > σ(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. |

Aromatic diamide diamines are useful precursors for the construction of larger molecules which are used in host-guest chemistry (Schneider &Yatsimirsky, 2008). Such diamines can bind neutral or anionic species using hydrogen bonds. We and others have reported several approaches for the synthesis of such type of diamines (Picard et al., 2001; Sessler et al., 2005a, 2005b; Katayev et al., 2007). In this work we present the synthesis and crystal structure of a diamine used by us recently to prepare anion selective receptors (Sessler et al., 2005a; Askerov et al., 2010).
The synthesis consists of the conversion of dicarboxylic acid into the corresponding chloride followed by coupling with 2-mercaptothiazoline (Fig. 1). The activated acid was transformed into (I) by the reaction with 1,2-phenylenediamine.
(I) crystallizes as a solvate with an acetonitrile molecule. The molecule possesses approximate Cs(m) intrinsic symmetry, with the mirror plane passing through the sulfur atom and the middle of the (Ph)C—C(Ph) bond (Fig. 2). Despite the main backbone of (I) being a long chain of conjugated bonds (CAr—N(H)—C(O)—C═C—C(O)—N(H)—CAr), it adopts a non-planar conformation due to the presence of various intra- and intermolecular hydrogen bonding interactions (Table 1). These hydrogen bonds result in twist configurations for both the amido and aminophenyl fragments relative to the central thiophene ring. The dihedral angles between the O1═C5—N1—H1 and O2═ C24—N3—H3 amido planes and the S1—C1—C2—C3—C4 thiophene ring plane are 16.08 (8) and 19.30 (11)°, respectively, while that between the N2—C7—C8—C9—C10—C11—C6 and N4—C26—C27—C28—C29—C30—C25 aminophenyl planes and the S1—C1—C2—C3—C4 thiophene ring plane are 39.16 (5) and 33.43 (6)°, respectively. The dihedral angles between the planes of the C12—C13—C14—C15—C16—C17 and C18—C19—C20—C21—C22—C23 phenyl substituents and the S1—C1—C2—C3—C4 thiophene ring plane are 62.55 (6) and 74.62 (5)°, respectively.
There are two intramolecular Namine—H···O hydrogen bonds in (I) closing the O1—C5—N1—C6—C7—N2—H2A and O2—C24—N3—C25—C26—N4—H4A seven-membered rings (Table 1, Fig. 2). In the crystal, the molecules form centrosymmetrical dimers through four N1—H1···N4i and N3—H3···N2i hydrogen bonds (Table 1, Fig. 3). The dimers are further linked into layers parallel to (100) both directly (via N4—H4B···O2iii hydrogen bonds, Table 1) and through the solvate acetonitrile molecules (via N2—H2B···N5ii and C32—H32A···O1 hydrogen bonds, Table 1) (Fig. 4).
