The title compound, C22H18N4O2S2, was characterized by 1H and 13C NMR, solid-state IR spectroscopy and X-ray crystallographic techniques. The determination reveals that the twisting modes of the two side arms are different [C—N—C—O and C—N—C—N torsion angles = −1.2 (3) and 1.1 (3)°, respectively, in one arm and 24.1 (3) and −5.1 (3)°, respectively, in the other]. The involves N—H⋯O and N—H⋯S hydrogen bonds.

All purchased chemicals and solvents were reagent grade and used without further purifcation. Melting points were determined with a Büchi 570 melting-point apparatus and were uncorrected. The 1H NMR spectra were measured with a Bruker AM-400 spectrometer, using tetramethylsilane as the internal standard. The solid-state IR spectra were recorded from KBr discs on a Nicolet spectrophotometer. To a mixture of 9.718 g (100 mmol) of potassium thiocyanate and 100 ml of acetone was added dropwise a solution of 14.071 g (100 mmol) of benzoyl chloride in 50 ml of acetone. The resulting mixture was stirred under reflux for 1 h and cooled to room temperature. A solution of 5.407 g (50 mmol) of 1,2-diaminobenzene in 20 ml of acetone was added. The yellow solution obtained was stirred at room temperature during 2 h. 300 ml of 1 N HCl was added to dissolve the precipitated KCl. A white solid appeared after five minutes. The compound was filtered and washed with 3 x 50 ml of water and dried under vacuum. Recrystallization from a mixture of methanol and chloroform (1:1) gave 18.52 g (85.7%) of the title compound.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s 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. |

The title compound, C22H18N4O2S2, was characterized by 1H and 13C NMR, solid-state IR and X-ray crystallographic techniques. The X-ray structure determination reveals that the compound crystallizes in the triclinic space group P-1 with one molecule in the asymmetric unit. The molecular geometry is illustrated in Fig. 1. The S1—C1 [1.6574 (18)Å], the S2—C8 [1.660 (2)Å], the O7—C16 [1.219 (2)Å] and O6—C9 [1.222 (2)Å] distances indicates that these correspond to double bonds and are comparable to those observed for 1-(biphenyl-4-carbonyl)-3-p-tolyl-thiourea [1.647 (3)Å for C—S, 1.217 (3) and 1.224 (3)Å for C—O respectively (Arslan et al., 2004)]. The C—N bond lengths are in the range [1.335 (2) - 1.435 (2)Å] and are shorter than the normal single C—N bond length, indicating double bond character (Avşar et al., 2003). The two side arms are not twisted in the same way. One of the arms is slightly twisted as reflected by the two torsion angle C1—N3—C9—O6 [-1.2 (3)°] and C9—N3—C1—N1 [1.1 (3) °]. The torsion angles C8—N4—C16—O7 [24.1 (3)°] and C16—N4—C8—N2 [-5.1 (3)°] in the other side arm indicate that this one is more strongly twisted. Intramolecular hydrogen-bond contacts involve the NH groups and the O atoms of the amide groups as well as the N atoms of the thiourea groups while intermolecular hydrogen-bond is observed between the NH groups and the S atoms of the thiourea groups (Table 2)
