The thione S atoms lie to the same side of the benzene ring and the carbonyl O atoms to the other. The most prominent feature of the crystal packing is the formation of inversion dimers mediated by N - H⋯S hydrogen bonds. One of the 2-methylpropyl groups is statistically disordered over two positions. © 2013 Selvakumaran et al.enArticle
