3-Acetyl-1-(2,3-dimethylphenyl)thiourea

Abstract

In the crystal structure of the title compound, C11H14N2OS, the conformation of the two N—H bonds is anti. The conformation of the C=S and the C=O bonds is also anti. Furthermore, the N—H bond adjacent to the benzene ring is anti to the ortho- and meta-methyl groups. The dihedral angle between the benzene ring and the side chain [N—C(= S)—N—C(=O)—C; maximum deviation = 0.047 (4) Å] is 81.33 (10)°. The NH hydrogen adjacent to the benzene ring and the amide O atom exhibit bifurcated intra- and intermolecular hydrogen bonding. In the crystal, molecules form inversion dimers, which are linked into chains via R22(12) and R22(8) networks.
