The title compound, C19H16N2O2S, was synthesized from furoyl isothiocyanate and N-benzylaniline in dry acetone and the structure redetermined. The structure [Otazo-Sánchez et al. (2001). J. Chem. Soc. Perkin Trans. 2, pp. 2211–2218] has been re-determined in order to establish the intramolecular and intermolecular interactions. The thiourea group is in the thioamide form. The thiourea group makes a dihedral angle of 29.2 (6)° with the furoyl group. In the molecules are linked by intermolecular C—H⋯O interactions, forming one-dimensional chains along the a axis. An intramolecular N—H⋯O hydrogen bond is also present.

The title compound, (I), was synthesized according to a procedure described by Otazo-Sánchez et al. (2001), by converting furoyl chloride into furoyl isothiocyanate and then condensing with N-benzylaniline. The resulting solid product was crystallized from ethanol yielding X-ray quality single crystals (m.p. 127–128°C). Elemental analysis for C19H16N2O2S found: C 59.95, H 4.60, N 10.74, S 11.21%; calculated: C 60.00, H 4.62, N 10.76, S 11.31%.

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. |

The importance of aroylthioureas is largely in heterocyclic syntheses and many of these substrates have interesting biological activities. Aroylthioureas have also been found to have applications in metal complexes and molecular electronics (Aly et al., 2007, Estévez-Hernández et al., 2006). The structure of the title compound (I), Fig.1, has been redetermined and the result adds significantly to the information already in the public domain (Otazo-Sánchez et al., 2001), especially about the intra and intermolecular interactions (not reported previously). The data and the refinement of the structure are also of better quality (present refinement: R: 0.0410 and wR: 0.1137; previous refinement: R: 0.1450 and wR: 0.2356). The main bond lengths and angles are within the ranges obtained for similar compounds (Koch et al., 2001; Pérez et al., 2008). The C2—S1 and C1—O1 bonds show typical double-bond character. However, the C—N bond lengths, C1—N1, C2—N1, C2—N2 are shorter than the normal C—N single-bond length of about 1.48 Å. These results can be explained by the existence of resonance in this part of the molecule. The central thiourea fragment (N1—C2—S1—N2) makes dihedral angle of 29,2(6)° with the furan carbonyl (O1—O2—C1—C3—C6) group, whereas the C7—C12 benzene ring is inclined by 84,7(6)°. The crystal structure is stabilized principally by the intramolecular N1—H···O2 hydrogen bond (Fig.1 and Table 1). In the crystal structure symmetry related molecules are linked by two different C—H···O1 interactions (C8—H···O1, 3.2<D<3.6 Å and θ>110°) and (C6—H···O1, 3.2<D<3.6 Å and θ>150°) to form one-dimensional chains along the a-axis (Fig. 2 and Table 1).
