1-(2-Chloro-5-nitrophenyl)-3-(2,2-dimethylpropionyl)thiourea

With the exception of the C atoms of two of the methyl groups of the tert-butyl substituent, all of the non-H atoms of the title compound, C12H14ClN3O3S, lie on a mirror plane. The 2-chloro-5-nitrophenyl and 2,2-dimethylpropionyl substituents are, respectively, cis and trans relative to the thiocarbonyl S atom across the two C—N bonds. Intramolecular N—H...O and C—H...S hydrogen bonds form S(6) ring motifs, also in the mirror plane. Despite the presence of two N—H subsituents, no intermolecular hydrogen bonds are observed in the crystal structure. Weak π–π contacts [centroid–centroid distances of 4.2903 (17) Å] involving adjacent aromatic rings link the molecules in a head-to-tail fashion above and below the molecular plane
