Redetermination of 1-cyclo-hexyl-3-(2-furo-yl)thio-urea.

ABSTRACT: The title compound, C(12)H(16)N(2)O(2)S, was synthesized from furoyl isothio-cyanate and cyclo-hexyl-amine in dry acetone, and the crystal structure redetermined. The thio-urea group is in the thio-amide 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 inter-molecular inter-actions. The trans-cis geometry of the thio-urea group is stabilized by intra-molecular hydrogen bonding between the carbonyl and cis-thio-amide 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 cyclo-hexyl group. There is also an intra-molecular hydrogen bond between the furan O atom and the other thio-amide
