1-Benzyl-3-(2-furo­yl)thio­urea

Abstract

In the title compound, C13H12N2O2S, the dihedral angle between the two aromatic ring planes is 87.52 (12)°. The mol­ecule shows an intra­molecular N—H(...)O hydrogen bond. The crystal structure is stabilized by inter­molecular N—H(...)S and C—H(...)O hydrogen bonding.

Comment

Substituted N-acylthioureas have been a subject of investigations, due to their ability to form stable metal complexes and as ionophores in potenciometric and amperometric sensors for Cd(II), Hg(II) and Pb(II) (Otazo et al., 2001; Estévez-Hernández et al., 2007). The title compound, (I) (Fig. 1), is another example of our newly synthesized furoylthiourea derivatives, which show outstanding complexation properties.

Compound (I) is a typical N,N'-disubstituted thiourea derivative with normal geometric parameters. The C2—S1 and C3—O1 bonds (Table 1) both show the expected double-bond character. The short values of the C2—N1, C2—N2 and C3—N2 bonds indicate partial double bond character.

The dihedral angle between the aromatic rings is 87.52 (12)°, and the angles with the thiourea plane are 86.67 (19)° for the benzene ring and 4.81 (12)° for the furan ring. An intramolecular N–H···O hydrogen bond is present (Table 2), forming a six-membered ring commonly observed in this type of compounds (Arslan et al., 2004; Khawar Rauf et al., 2007). The crystal structure of (I) is stabilized by intermolecular N—H···S and C—H···O hydrogen bonding (Table 2).

Experimental

The title compound, (I), was synthesized according to a procedure described by Otazo et al. (2001) by converting furoyl chloride into furoyl isothiocyanate and then condensing with the appropriate amine. The resulting solid product was crystallized from a dichlorometane-methanol (1:1) mixture yielding X-ray quality single crystals. Elemental analysis for C13H12N2O2S found: C 67.73, H 4.75, N 8.23, S 9.34%; calculated: C 67.86, H 4.46, N 8.33, S 9.52%

Refinement

H atoms were placed in calculated positions with C–H = 0.95 Å (aromatic), N–H = 0.88 Å and C–H = 0.99 Å (methylene), and refined in riding model, Uiso(H) = 1.2Ueq(C,N).

Special details

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.
