Three anilides of 2,2′-thiodibenzoic acid

The structures ofN,N′-bis(2-methylphenyl)-2,2′-thiodibenzamide, C28H24N2O2S, (Ia),N,N′-bis(2-ethylphenyl)-2,2′-thiodibenzamide, C30H28N2O2S, (Ib), andN,N′-bis(2-bromophenyl)-2,2′-thiodibenzamide, C26H18Br2N2O2S, (Ic), are compared with each other. For the 19 atoms of the consistent thiodibenzamide core, the r.m.s. deviations of the molecules in pairs are 0.29, 0.90 and 0.80 Å for (Ia)/(Ib), (Ia)/(Ic) and (Ib)/(Ic), respectively. The conformations of the central parts of molecules (Ia) and (Ib) are similar due to an intramolecular N—H...O hydrogen-bonding interaction. The molecules of (Ia) are further linked into infinite chains along thecaxis by intermolecular N—H...O interactions, whereas the molecules of (Ib) are linked into chains alongbby an intermolecular N—H...π contact. The conformation of (Ic) is quite different from those of (Ia) and (Ib), since there is no intramolecular N—H...O hydrogen bond, but instead there is a possible intramolecular N—H...Br hydrogen bond. The molecules are linked into chains alongcby intermolecular N—H...O hydrogen bonds.</jats:p
