Redetermination of 1-cyclo­hexyl-3-(2-furo­yl)thio­urea

The title compound, C(12)H(16)N(2)O(2)S, was synthesized from furoyl isothio­cyanate and cyclo­hexyl­amine in dry acetone, and the crystal structure redetermined. The thio­urea group is in the thio­amide form. The structure [Otazo-Sánchez et al. (2001 ▶). J. Chem. Soc. Perkin Trans. 2, pp. 2211–2218] has been redetermined in order to establish the intra- and inter­molecular inter­actions. The trans–cis geometry of the thio­urea group is stabilized by intra­molecular hydrogen bonding between the carbonyl and cis-thio­amide groups, resulting in a pseudo-S(6) planar ring which makes a dihedral angle of 3.24 (6)° with the 2-furoyl group and a torsion angle of −84.3 (2)° with the cyclo­hexyl group. There is also an intra­molecular hydrogen bond between the furan O atom and the other thio­amide H atom. In the crystal structure, mol­ecules are linked by inter­molecular N—H⋯O hydrogen bonds, forming chains along [010].
