The general method used for the synthesis of the amides was as follows. Thionyl chloride (2 ml) was added to 2,2'-thiodibenzoic acid (0.49 g, 1.8 mM mmol?) dissolved in dichloromethane (20 ml) and the resulting solution was heated at reflux for 2 h. The excess thionyl chloride was removed by distillation and the resulting double acid chloride used without further purification. The aniline (2-methylbenzenamine, 2-ethylbenzenamine or 2-bromobenzenamine) (3.6 mM mmol?) was added to the freshly prepared 2,2'-thiodibenzoic acid chloride. The mixture was heated at reflux for 2 h and then stirred at room temperature for 24 h. The resulting precipitate was filtered off, washed with water and ethanol, dissolved in warm acetonitrile (15 ml), filtered, and the filtrate cooled and left in the dark. After two weeks, crystals of the anilides had deposited.

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. |

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. |

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. |

Diaryl sulfides have attracted much attention because of their synthesis (Eichman & Stambuli, 2011), reactivity (Kondo & Mitsudo, 2000) and biological importance (Jiang et al., 2003). They also constitute an important class of pharmaceutical agents (Goordazi et al., 2010; Fernando-Gomez et al., 1995; Girault et al., 2001; Stump et al., 2007). The three-dimensional structures of some diaryl sulfides have been determined by X-ray crystallography (Muhammad et al., 2008) and were found to adopt equatorial, planar or skew conformations (Kucsman et al., 1984). In the present study, three 2,2'-thiodibenzamides were synthesized by the reaction of 2,2'-thiodibenzoic acid chloride with three anilines, 2-methylbenzeneamine, 2-ethylbenzeneamine and 2-bromobenzeneamine, namely N,N'-bis(2-methylphenyl)-2,2'-thiodibenzamide, (Ia), N,N'-bis(2-ethylphenyl)-2,2'-thiodibenzamide, (Ib), and N,N'-bis(2-bromophenyl)-2,2'-thiodibenzamide, (Ic) (Fig. 1). A paper describing these amides and other related substances, and their biological properties, has been accepted for publication elsewhere (Moosun et al., 2013). X-ray diffraction analyses have now been carried out to ascertain the constitution of the molecules, as well as to determine the effect of different substituents on the conformation and configuration of the synthesized molecules.
Considering first the diaryl sulfide units in the three structures, the C9—S1—C14 angles vary little, being 104.92 (6), 103.04 (6) and 103.9 (1)° for (Ia), (Ib) and (Ic), respectively. The relative orientations of the two benzene rings around S are described by two dihedral angles, C10—C9—S1—C14 and C15—C14—S1—C9, where `C—C' are two C atoms of one ring with the second attached to S and `C' is the first C atom of the other ring, attached to S. Thus, for (Ia), the values are -48.9 (1) and 39.0 (1)°, for (Ib) -42.7 (1) and -57.5 (1)°, and for (Ic) -16.0 (3) and -86.8 (3)°. These dihedral angles measure the extent to which the benzene rings are not coplanar with the C—S—C plane.
Moving away from the S atom, the orientation of the amide carbonyl groups with respect to the their attached benzene rings is measured by the torsion angle O—C—C—C, where O—C is the carbonyl group and the last two C atoms are in the benzene ring. There are two such angles, O1—C7—C8—C13 and O2—C20—C15—C14, for each of the three amides: for (Ia) these are -45.4 (2) and -49.0 (2)°, for (Ib) -45.4 (2) and -51.3 (2)°, and for (Ic) -111.7 (5) and 45.3 (3)°. Thus, in each case, there is considerably reduced overlap between the carbonyl π-system and that of the attached benzene ring, i.e. little conjugation.
The sums of the angles at the N atoms are 360.0 and 359.1° for (Ia), 360.0 and 359.6° for (Ib), and 360.5 and 359.5° for (Ic). Clearly, the six amide N atoms are all essentially planar. This allows one to measure the extent of amide resonance by the torsion angles C—N—C—O, where the first C atom is the benzene ring C atom to which the N atom is attached. There are thus two torsion angles for each compound, viz. C1—N1—C7—O1 and C21—N2—C20—O2: -10.4 (2) and 2.6 (2)° for (Ia), -9.4 (2) and 3.4 (2)° for (Ib), and -0.8 (7) and 0.7 (5)° for (Ic), respectively. Each of the six amide units is very close to being planar, which is ideal for amide resonance.
At the extremities of the three structures, it is relevant to ask to what extent the nitrogen p-orbital interacts with the π system of the attached benzene ring, especially remembering that that ring has an ortho substituent. This can be measured from the C—N—C—C torsion angles (where the first C is the carbonyl C atom and the last two are the attached C atoms of the benzene ring), i.e. C7—N1—C1—C6 and C20—N2—C21—C22: -36.5 (2) and -62.5 (2)° for (Ia), -43.9 (2) and -92.0 (2)° for (Ib), and -0.6 (7) and 142.6 (3)° for (Ic), respectively. These torsion angles show that in only one amide out of six is there good overlap between the nitrogen lone pair and the attached benzene ring, namely, the amide containing atom N1 in (Ic).
We have also estimated the similarity between these three structures by overlaying them with one another (Fig. 2). Structures (Ia) and (Ib) are quite similar, with an r.m.s. difference of 0.29 Å when fitting the S, N, O and C7–C20 atoms (the terminal benzene rings were omitted; see figure in Supplementary Materials). This finding is in accord with the comparison of torsion angles starting at the central S1 atom and working out to the extremities of the molecules shown above, i.e. that the conformations of the central portions of molecules (Ia) and (Ib) are similar and that the molecules only deviate from one another by a large amount in the C20—N2—C21—C22 torsion angle. The bromine-containing diamide, (Ic), is much less similar with either (Ia) or (Ib), with r.m.s. differences for the same atoms of 0.90 and 0.80 Å, respectively (see figure in Supplementary Materials). This is consistent with the fact that all the torsion angles of (Ic) are quite different from those of (Ia) and (Ib)..
The differences in the conformations of the three molecules can be rationalized in terms of the similarities and differences in their hydrogen-bonding interactions. The central parts of molecules (Ia) and (Ib) are similar due to the intramolecular N1—H1···O2 hydrogen bond seen in both structures (Figs. 1a, 1b, 3a and 3b). In (Ic), this intramolecular interaction does not occur, but instead a possible intramolecular N1—H1···Br1 bond is observed (Figs. 1c and 3c). The geometry of this hydrogen bond, with an N1—H1···Br1 angle of 120 (4)°, indicates that its stabilization energy is low and therefore it may not be significant (Wood et al. 2009).
Due to the differing intramolecular hydrogen bonding observed for (Ic) compared with (Ia) and (Ib), the conformation of the central portion of the molecule of (Ic) is not similar to those of (Ia) and (Ib). The hydrogen-bonding patterns otherwise differ in all three molecules. In (Ia), an intermolecular N2—H2···O1 hydrogen bond [symmetry code (x, -y + 3/2, z - 1/2)] links the molecules into chains along c (Fig. 3a). In (Ib), the molecules are linked into chains along b by an intermolecular N—H···π contact, N2—H2N···Cg1 [Cg1 is the centroid of the C1–C6 benzene ring; symmetry code (-x + 3/2, y - 1/2, -z + 3/2)] (Fig. 3b). In (Ic), the molecules are linked into chains along c by an intermolecular hydrogen bond N2—H2N···O2(x, -y + 3/2, z - 1/2) (Fig. 3c).
