1-(3-Chloro-phen-yl)-3-(2,6-dichloro-benzo-yl)thio-urea
Abstract:
The structure of the title compound, C(14)H(9)Cl(3)N(2)OS, is composed of discrete mol-ecules with bond lengths and angles quite typical for thio-urea compounds of this class. The plane containing the thio-carbonyl and carbonyl groups subtends dihedral angles of 48.19 (3) and 87.51 (3)° with the planes formed by the 3-chloro and 2,6-dichloro-phenyl rings, respectively; the dihedral angle between the two benzene ring planes is 45.32 (3)°. An intra-molecular N-H⋯O hydrogen bond stabilizes the mol-ecular conformation and the mol-ecules form inter-molecular N-H⋯S and N-H⋯O hydrogen bonds, generating a sheet along the a axis.
