N-(2-Furo-yl)-N'-(2-pyrid-yl)thio-urea.

ABSTRACT: The title compound, C(11)H(9)N(3)O(2)S, crystallizes with two independent mol-ecules in the asymmetric unit. The central thio-urea core makes dihedral angles of -3.3 (3) and 0.6 (3)° with the furan carbonyl groups in each mol-ecule, whereas the pyridine ring is inclined by 4.63 (2) and 11.28 (7)°, respectively. The trans-cis geometry of the thio-urea fragment is stabilized by an intra-molecular N-H⋯N hydrogen bond between the H atom of the cis-thio-amide group and the pyridine N atom. In the crystal structure, inter-molecular bifurcated N-H⋯S and N-H⋯O hydrogen bonds form centrosymmetric tetra-mers extending along the b axis.

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

Project description: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 H atom. In the crystal structure, mol-ecules are linked by inter-molecular N-H⋯O hydrogen bonds, forming chains along [010].

1-(2-Furo-yl)-3-(2-meth-oxy-4-nitro-phen-yl)thio-urea.

Project description:The asymmetric unit of the title compound, C13H11N3O5S, contains two independent mol-ecules, which are linked by a pair of inter-molecular N-H⋯S hydrogen bonds, forming an R2(2)(8) ring motif.

The dihedral angles between the furoyl and benzene rings in the two mol-ecules are 3.97 (10) and 5.98 (9)°. The trans-cis geometry of the thio-urea group is stabilized by three intra-molecular N-H⋯O hydrogen bonds involving carbonyl and meth-oxy O atoms with the H atom of the cis-thio-amide group and between furan O atom and the other thio-amide H atom. There is also a weak intra-molecular C-H⋯S inter-action in each mol-ecule.

1-[3,5-Bis(trifluoro-meth-yl)phen-yl]-3-(2-pyrid-yl)thio-urea.

Project description:The title compound, C(14)H(9)F(6)N(3)S, exhibits a nearly planar conformation in the solid state, with a dihedral angle between the planes of the benzene and pyridine rings of 14.86 (3)°. The pyridine N atom allows for the formation of a six-membered N-H⋯N(py) hydrogen-bonded ring, thus forcing the two amide H atoms of the thio-urea group to point in opposite directions. The second N-H group forms an inter-molecular N-H⋯S hydrogen bond with the S atom of an adjacent mol-ecule. The F atoms of the two trifluoro-methyl groups display rotational disorder around the C-CF(3) axis, with an occupancy ratio of 0.54 (1):0.46 (1).
